Synthesis of Control Algorithms for a Permanent Magnet Synchronous Motor in Sliding Mode

Abstract

The paper considers the synthesis of algorithms for controlling a permanent magnet synchronous motor in the sliding mode based he the concept of inverse problems of dynamics, which provide low sensitivity that parametric and coordinate disturbances. The basis of the method is the idea of reversibility of the direct Lyapunov method for stability research, which allows finding control laws in which the closed circuit has a predetermined Lyapunov function. The Lyapunov function is the instantaneous energy value. A characteristic feature of the presented control laws is the absence of object parameters in them. This ensures high control quality, dynamic decomposition of the interconnected system, and facilitates the practical implementation of control algorithms.
