基于WNN 参数整定的ADRC 在火箭炮伺服系统中的应用

针对多管火箭炮交流伺服系统存在变负载、强耦合和不确定性扰动等非线性问题，提出一种优化型小波神经网络自抗扰控制器(WNN-ADRC)。简化电流环节得到被控系统的数学模型，将小波神经网络(wavelet neuralnetwork，WNN)嵌入自抗扰控制器中进行参数整定，利用分层调整学习速率的方法优化小波神经网络的学习算法得到WNN-ADRC，采用WNN-ADRC 控制火箭炮伺服系统，实现对非线性特性的精准估计和补偿。数值仿真结果表明：相对于传统的自抗扰控制器，WNN-ADRC 能改善伺服系统的静态响应和动态性能，具有响应速度快、控制精度高的优点。

Application of ADRC Based on WNN Parameter Tuningin Rocket Launcher Servo System

An optimized wavelet neural network active disturbance rejection controller (WNN-ADRC) is proposed tosolve the nonlinear problems of multiple rocket launcher AC servo system, such as variable load, strong coupling anduncertain disturbance. The mathematical model of the controlled system is obtained by simplifying the current link, and thewavelet neural network (WNN) is embedded into the ADRC for parameter tuning, and the learning algorithm of the WNN isoptimized by using the method of hierarchically adjusting the learning rate to obtain the WNN-ADRC. The WNN-ADRC isused to control the servo system of the rocket launcher to realize the accurate estimation and compensation of the nonlinearcharacteristics. The numerical simulation results show that the WNN-ADRC can improve the static response and dynamicperformance of the servo system, and has the advantages of fast response and high control precision compared with thetraditional ADRC.
