Appendix "Contract for the identification of dynamical characteristics of multidimensional and of multiply FACILITIES MANAGEMENT ACCORDING passive experiment"

APPENDIX 1. REQUIREMENTS FOR MATERIALS expel NIC

All materials submitted in electronic form shall be prepared on an IBM-compatible computer and consist of

- Text file (format MS WORD) in any form containing a brief verbal description of the object control of its use, as well as other significant from the point of view of the customer information. Information must not contain information falling under the term "classified information".

files containing raw data prepared in accordance with the following requirements.

A.1.1. All implementations of the input and output signals of the control channels to be recorded simultaneously, in the normal functioning of the real multidimensional and object management of multiply on the observation interval, when the proper motion of the object can be neglected. Be excluded from the implementation of its own motion of an object management, observed after the control object to the work. Are not given the initial data obtained by mathematical modeling.

Clause 1.2. Allowed to provide baseline data on A.1.1 for the one object of control. In the cover letter must cite that source data transmitted owned one-dimensional control.

Clause 1.3. Number of realizations of input signals A.1.1 must necessarily be equal to the actual number of controlled entrances to the multidimensional and object management of multiply. For example, a control has 5 inputs and 5 outputs, which in the normal functioning of the observed non-zero signals. Customer interested in the dynamic characteristics of only the first three inputs and outputs. Despite this, the customer is obliged to send to the Contractor's implementation of all input signals observed in the five entrances. Implementation of signals observed in the last two outputs, the Customer may not send.

Clause 1.4. Software package, which implements the method of identifying ASVT51, designed for the identification of multiply and multidimensional control objects, which have a maximum of 10 inputs and 10 outputs. If the customer requires more dimension to the input or output, the Contractor may, by prior arrangement with the customer to adapt your application package to the necessary dimensions.

A.1.5. All discrete samples implementations signals must be in digital form on any of the three types (double, float, int) for the numbers defined in the programming language C or C++

P.1.6. Digitizing the analog input and output signals of the sensors must exclude some disturbance generated by the substitution frequencies. For this purpose between the sensor and the input of the ADC must be set to analog low-pass filter (LPF), shielded from external interference. The first sampling rate must be at least twice the frequency with which the low-pass filter almost completely suppresses high frequency components of signals on a finite observation interval. Discrete samples filtered digital output low pass filter with a bandwidth not exceeding the bandwidth of the analog sensor. Output ADC is not all discrete samples, and certain of the account (decimation)..

P.1.7. The sampling rate Fkv after decimation should be equal Fkv = 21Fv, where Fv - limiting frequency spectrum of the original signal. This is the optimal sampling frequency in terms of the best combination of price and quality measurement of the boundary of the harmonic component of the generalized velocity. It is 10.5 times higher sample rate, determined by Theorem Kotelnikov. Not allowed to decrease below the sample rate equal 10Fv. Implementations should not signal harmonics with frequencies equal to Fv and higher frequencies.

P.1.8. The frequency characteristics of the analog low-pass filter installed between the sensor and the ADC input and output of the identified control channel must have the same frequency transfer functions. Not doing so will cause a systematic error in the determination of the dynamics of the investigated control channels that are difficult to interpret.

P.1.9. Primary sensors analog signals must be linear and without inertia elements in each control channel. Not doing so will cause a systematic error in the determination of the dynamics of the investigated control channels that are difficult to interpret.

1.10. If the customer can not meet the condition for P.1.8 and P.1.9, then the need for dynamics control channel without affecting the dynamic properties of the analog low-pass filters and sensor signals, the Client NIC sends the values ​​of frequency transfer functions of analog low-pass filters and frequency values transfer functions of sensor input and output signals of the control channel is identified, taken at the frequency specified by the Contractor.

P.1.11. Customer prepares raw data to be sent to the Contractor by the training data PODAN51z.exe (the Program), developed by the Contractor.

P.1.12. For a correct solution of the problem of verification by mathematical models and multidimensional object management of multiply indirect method according to the passive experiment to use the new implementation synchronously recorded input and output signals that are independent of synchronization of recorded input and output signals, used earlier to solve the identification problem. With the agreement on the solution of the problem of verification Customer sends NIC new source data satisfying the above mentioned requirements and the requirements described in the Appendix 3.

APPENDIX 3. Verification of identification.

Verification - translated from Latin means - the authenticity of the certificate. Solutions to the problem of verification of dynamic characteristics of a control depend on a priori information about the exact dynamic characteristics, dimensions and mnogosvyazannosti facility management as well as the method of obtaining the source data. Consider the problem of verification on a one-dimensional linear stationary control object according passive experiment. Verification is performed by the direct method when you know the mathematical model of the object management. Verification of the direct method is performed by comparing the true mathematical model of control object with a mathematical model, the resulting identification. Direct verification method is applied, as a rule, the solution of test problems of identification when used deliberately known mathematical model of the object management and mathematical models of the observed signals. In the real world solution to the problem of verification is complicated by the fact that there is no a priori information about the exact mathematical model of the object management. In such conditions, the verification can be done indirectly. After solving the problem of identification becomes known mathematical evaluation model of the object. For a known input signal and evaluate the mathematical model of the dynamic characteristics of the control object can be calculated to find an estimate output. By the degree of agreement between the calculated and the actual output is judged on the degree of overlap identified mathematical model with its exact value. However, there are cases where the coincidence output rating of the mathematical model can arbitrarily very different from its true value. It is easy to show that this phenomenon can occur when the indirect method for verifying the input signal is used, which was used to solve the problem of identification.

For a correct solution of the indirect method of verification is necessary that the spectrum of the input signals to be used for solving the problem of identification and verification tasks that generate different ideally orthogonal to each other spectral functions. Orthogonal spectral functions generate orthogonal, and, therefore, are independent random processes.

In solving the problem of verification of multiply and multivariate control object indirect method according to passive experiment to use the implementation of the signals, which are observed at all the entrances. In this case, a plurality of input signals to be used to solve the problems of identification and verification should be a set of independent random processes.
