PID控制器的激光漂移量优化

Lasers drift optimization of PID controller

传统PID控制器的激光漂移抑制方法对漂移抑制性能不好,提出基于自适应Lyapunove泛函修正和稳态误差补偿的PID控制器的激光漂移抑制算法。对PID激光惯性制导控制器进行被控对象描述和控制参量分析,在小扰动条件下构建三层变结构PID神经网络结构进行控制目标函数优化,采用自适应Lyapunove泛函进行控制稳定性设计,得到最佳控制律。仿真结果表明,采用该控制算法进行激光惯性制导控制,能有效抑制激光漂移带来的控制失真和扰动误差,提高控制精度,各控制目标参量具有较好的误差修正效果,控制品质较高。

Traditional PID controller of laser drift suppression method for drift suppression performance is bad. For this, put forward a kind of based on adaptive Lyapunove functional correction and steady-state error compensation of laser drift suppression algorithm of PID controller, laser inertial guidance of PID controller to control the controlled object description and parameter analysis, under the condition of small disturbance building three layer variable structure PID control objective function optimization, neural network structure using adaptive Lyapunove functional design, the stability of control to get optimal control law. The simulation results show that this control algorithm is adopted to improve the laser inertial guidance control, can effectively restrain the laser drift control distortion and disturbance error, improve the control precision, the control target parameters has good error correction effect, higher control quality.
