Synthesis of a Quasi-Optimal in Speed Relay-Modal Position Control System, Based on the N-I Switching Method

The mathematical apparatus of the N - i switching method, due to its simplicity, made it possible to find out relations between the parameters of relay-modal and quasi-optimal in speed sliding mode control systems. Initially, this result was formulated for control systems of neutral-stable dynamic objects. This paper presents a comparative study of the dynamics of systems with different settings. Based on it, an adaptation of the optimization method for the speed of relay-modal systems to the synthesis of a regulators cascade for positional electric drive is proposed.
