Device for the Experimental Determination of Control Objects' Mathematical Models

Abstract

Authors review methods of determining a plant’s mathematical model. Then, they show a numerical method of pulse automatic control systems’ (ACS) identification, focused on computer technology, the interpolation procedure and iterative methods of approximation to the desired solution. The basis of the approach is the method of inverse problems of dynamics and real interpolation method for calculating the linearized dynamical systems. An algorithm and the mobile device designed for the identification of facilities management in operational conditions are proposed. There is results’ application in the conclusion.

Mobile Devices for Plants Models Obtaining with the Possibility of Data Transition (by Ethernet)

“…The basic algorithm of the program remains unchanged, so the transfer functions obtained in the same way as it was described in [8]. However, it is necessary to chooce the appropriate data trasmition protocol that ensures the delivery of data.…”

“…The identification device can solve the problem of mobile identification and the automatic control systems tuning. The algorithms and mathematical apparatus used in this device are presented in [7,8]. Consider the hardware implementation structural scheme of the device.…”

Hardware Implementation Tasks to Configure Regulators

“…To solve the problem has developed a method descriptions dynamic systems, results-oriented on digital computing and numerical methods of action over such descriptions. This method, called the real interpolation method (RIM), allowed more than halve amount of computational operations [5,6]. Such advantage allowed to create of the compact mobile device which has made possible automated configuring regulators.…”

Getting the Mathematical Models of Automatic Control Systems with Non-Uniform Sampling Period

“…The task is to obtain a discrete TF of the form Assign the interpolation nodes for image-functions, using the recommendations [8]. Choose evenly distributed node values: 1, 4.5, 8, 11.5.…”
