Optimization and Simulation of Short-range Loitering Missile Attitude Control System

摘要:

近程巡飞弹姿态控制系统是一个非线性、时变性及耦合性的复杂控制系统,是近程巡飞弹武器系统型号研制的关键技术之一;传统的PID控制在不同巡飞状态下调节稳定性较差、响应时间慢、影响姿态控制的稳定性和机动性;针对近程巡飞弹姿态控制系统中PID控制参数不可调,自适应、抗干扰性能较差等问题,引入了自适应模糊PID控制方法,使系统在不同巡飞姿态和干扰条件下能够实时整定PID的三个控制参数,提高系统的控制性能;在此基础上设计了近程巡飞弹的姿态角控制回路,并以俯仰角为例,在Matlab/Simulink平台下建立仿真模型,进行仿真实验;仿真结果显示,采用自适应模糊PID的控制方法,系统控制性能更好,抗干扰能力和自适应能力优于传统PID控制,减小了巡飞过程中姿态角的波动情况。

Abstract:

This paper focuses on Attitude control system of proximity patrol missile which is nonlinear, time-varying and complex coupling control system, and it is one of the key of short-range patrol missile weapon system developed. Traditional PID control is less stable and have slow response time, affect the stability and maneuverability of attitude control. Due to parameters of PID control are not adjustable, poor adaptive anti-jamming performance issues for short-range missile patrol attitude control system. An adaptive fuzzy PID control method is provided to improve the control system performance by tuning PID parameters real-time. Attitude angle control loop of short-range patrol missile is designed, and taking pitch angle for example, build the simulation model in Matlab / Simulink platform, by comparing the traditional PID control, analysis the controller performance. The simulation results show that the adaptive fuzzy PID control method, the system control performance is better, anti-interference ability and adaptive ability is superior to the traditional PID control, which reduces the fluctuation of loitering during attitude angle.
