调节阀DDVC电液执行机构复合控制研究

摘要

In this paper,the new DDVC electro - hydraulic actuator is researched. A PID - corrected compound control strategy combining optimal state feedback control with observer - estimated load disturbance feed - forward control is presented. The results of simulation indicate that the actuator has high response speed and good dynamic and static characteristics.%研究了新型DDVC电液执行机构,提出将PID校正最优状态反馈控制与观测器预估干扰前馈控制相结合的复合控制应用于该执行机构.仿真结果表明该执行机构响应速度快,动静态性能良好.
