液粘调速系统双闭环控制设计

Study on Control Strategy of Hydroviscous Driver System in Panzer Vehicle

基于液粘调速系统理论,建立了由电液比例减压阀和液粘离合器组成的液粘调速系统Simulink模型,以控制在液粘调速过程中负载转速和电液比例减压阀压力输出稳定为目的,设计了以转速和油压为控制目标的液粘调速双参数控制策略,并通过仿真计算与试验验证,结果表明,该控制策略液粘调速系统稳态工作时转速输出稳定,动态控制特性效果良好.

Based on the theory of hydroviscous driver system, the driver system Simulink model composed of electro-hydraulic proportional valve and viscous clutch was established. To control he steady output of load speed and oil pressure, the double parameters control strategy of hydroviscous driver system was diesigned. The results of simulation and examination show that the error of control goal was small during the steady work state, and the impact of dynamic control process was well .
