Control System Optimization Design of Electrical Control Actuator about Simple Guidance Mortar Projectile

关于电动舵机控制系统优化问题,针对电动舵机系统非线性多变量所导致响应速度较慢,依据简易制导迫击炮弹飞行过程中舵机控制的实际响应情况,为优化电动舵机控制系统快速响应特性,利用模糊自适应整定控制算法确定实现对相关参数的最佳调整,设计出一种适用于简易制导迫击炮弹电动舵机的模糊控制器,利用matlab软件进行仿真。结果表明,优化后的电动舵机控制系统响应速度大幅提高,同时有效地改善了系统的幅频曲线和相频曲线等频域特性。最后通过半实物仿真验证了改进方法的有效性,为简易制导迫击炮弹研制提供了理论基础。

As the strong non - liner and multi - variables, electric control actuators are often accompanied with low response time. Aiming at the actual condition of the simple guidance mortar projectile of the electrical control ac- tuator response, this papper designed a fuzzy self - turning controller suitable for the simple guidance mortar projec- tile in order to improve the reponse property of electric actuator control system. Relevant parameters were adjused by means of fuzzy self - turning control. The Matlab simulation results show that the reponse precision and the effect of control system are better. At the same time, the domain characteristics of the system are also improved. Finally, the results of both simulation and relative experiments verify the validity of the proposde strategy. It can provide some ba- sis for the design of simple guidance mortar projectile.
