On the synthesis of passive–adaptive systems for electric drive control

Abstract

A new approach to synthesis of passive–adaptive electromechanical control systems is proposed. Decomposition of a control system structure into two subsystems, which solve a uniform problem of finite control, but have various functions, is a feature of the presented approach. The first subsystem is a control system of an electric drive, and it carries out the task of finite control that is invariant to the reference signals in the traditional statement of linear discrete–continuous systems. The second subsystem is an adaptive reference model that forms a criterion that is optimal in terms of performance and accuracy of the phase coordinate vector of an electric drive with restriction of them to acceptable levels. A discrete–continuous system of electric drive control and a functional structure of a passive–adaptive electromechanical system are set up in the MexBIOS Development Studio simulating the modeling environment. The results of simulation showed that there is an acceptable quality of system operation in both linear and nonlinear areas of operation when working out additive increments of setting the position of the drive shaft changing at random points of time. The synthesized system has low sensitivity to changes in the parameters of the object of electromechanical control.
