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。
The traditional PID controller’s laser drift suppression method is not good for the drift suppression performance. A laser drift suppression algorithm based on adaptive Lyapunove functional correction and steady-state error compensation is proposed. PID controlled inertial guidance controller for controlled object description and control parameter analysis, under the conditions of small disturbance to build three-layer variable structure PID neural network structure for the control objective function optimization, the use of adaptive Lyapunove functional stability control design obtained Best control law The simulation results show that using the control algorithm to control the laser inertial guidance can effectively control the control distortion and disturbance error caused by the laser drift and improve the control accuracy. The control target parameters have better error correction effects and higher control quality.
