摘　　要：针对传统的气动位置控制方法在工程应用中难以实现快速、精确的控制,提出基于最优状态反馈的电气比例控制方法,该方法使用状态观测器,对系统进行状态估计,并以极点配置和线性二次型性能原理确定最优状态反馈控制量,使系统闭环输出达到最佳。仿真实验结果表明,此方法结合状态空间反馈法以及线性二次型最优控制的优点,能反映气动位置系统中独立变量的变化,确定系统的内部运动准状态,而且可以使系统快速达到稳定状态,更好地满足气动位置控制在工程应用中的要求。The traditional cybernetics could hardly to realize fast and exact control on practical application of pneumatic position control An technique based on optimal state feedback of electrical proportional was brought forward.This technique made use of state observation controller to estimate system state,then the closed loop output reached an optimal control by collocating apices and linear-quadratic principle which corfirmed the optimal state feedback vectors.Simulation results showed this method combined excellence with state-space feedback and linear-quadratic optimization principle,reflected changes of self-existent variable,ensured system internal movement state,and expediently dealt with initialization data,made the system attain to stabilization as soon as possible.
