基于抗扰动补偿的转台伺服系统准滑模控制研究

Turntable Servo System Quasi-sliding Mode Control Research Based on Disturbance Compensation

针对飞行模拟转台伺服系统中存在的内部和外部扰动，在分析它们对转台伺服系统影响基础上，采用线性连续准滑模控制（LCPSM）和状态立方反馈准滑模控制（SCFPSM）两种方法对转台伺服系统进行了抗扰动补偿控制，通过与传统PID控制方法和常规滑模变结构控制方法的比较证明准滑模控制方法对于转台伺服系统中的参数摄动和外部摩擦等扰动因素具有良好的抑制和补偿作用，消除了常规滑模变结构控制中的抖振现象。

Flight Simulator Servo System for the existing internal and external disturbances,the analysis of their impact on the servo system based on the quasi-sliding mode control for linear continuous（LCPSM）and the quasi-sliding mode feedback control of the state cubic（SCFPSM）two Methods carried out on the servo system disturbance compensation control with traditional PID control method and conventional sliding mode control method comparison demonstrate quasi-sliding mode control method for servo system parameter perturbation and external friction, and disturbance factors Good suppression and compensation,elimination of the conventional sliding mode control chattering.
