Abstract

According to the permanent magnet synchronous motor dynamic event triggering terminal sliding mode control method and device, in order to eliminate the requirements of lumped interference and parameter uncertainty possibly existing in a permanent magnet synchronous motor system for priori knowledge, an adaptive neural network (ANN) is introduced into a terminal sliding mode control (TSMC) scheme. In addition, in order to reduce the communication burden of a networked system, a dynamic event triggering mechanism considering a neural network estimation error is adopted to schedule signal transmission between a speed sensor and a remote sliding mode controller. And the Zeno phenomenon of a dynamic event triggering mechanism is eliminated through explicit analysis. It is further proved that by selecting proper sliding mode parameters, the provided control strategy can ensure that sliding mode variables are converged to an actual sliding mode area, and the speed tracking error is finally bounded. Finally, according to simulation and experiment results, the control algorithm provided by the invention can well realize a predetermined target.

Description

technical field [0001] The present invention relates to the technical field of permanent magnet synchronous motors and the technical field of networked control, in particular to a method and device for dynamic event-triggered terminal sliding mode control of permanent magnet synchronous motors. Background technique [0002] Mobile permanent magnet synchronous motors (PMSMs) play a key role in various industrial fields such as aerospace, robotics, and electric vehicles due to their excellent performance. It should be pointed out that the dynamics of PMSM have highly coupled and nonlinear characteristics, as well as parameter uncertainties and external disturbances. Therefore, it is difficult to achieve high-performance control of permanent magnet synchronous motors by using traditional control methods (such as proportional-integral-differential method). Recently, some nonlinear control strategies have been adopted to bypass the above obstacles. Among many nonlinear control ...
