摘　　要：基于滑模控制算法和卡尔曼滤波算法设计了离合器从动盘测试机的电控系统控制器。通过机理分析和模型参数辨识建立了系统的简化数学模型,根据简化数学模型设计了采用给定补偿、力前馈和基于指数趋近律的滑模变结构控制构成的复合控制器和卡尔曼滤波数字滤波器,构成电控系统的控制器。经实验验证,与复合PID控制相比,在加载力和工作现场干扰作用下系统具有较好的稳态精度和动态特性。A controller for the control system of clutch disc tester is designed based on sliding mode control and Kalman filters algolithm.A simplified mathematical model has been established through mechanism analyzing and model parameter identification,on which the controller for the electrical control system is constructed with composite controller and Kalman digital filters.Within which the composite controller is composed of speed feed forward,force feed forward and sliding mode control.Compared with composite PID control,the system is proved through test that works well with stable precision and dynamic characteristics even under load and the interference in working site.
