摘要
针对二维弹道修正引信乒乓舵机控制周期不稳定的问题,提出了基于线性二次型调节器(LQR)控制算法的乒乓舵机控制方法。首先对乒乓舵机进行数学建模,其次将乒乓舵机的数学模型写成状态空间描述的形式,再判断乒乓舵机的状态空间描述是否满足LQR控制算法的应用条件,最后应用LQR控制算法得到最优控制律。仿真结果表明,基于LQR控制算法的乒乓舵机控制方法与传统的三环PID控制方法相比,调节时间短,不存在超调,控制精度高,同时所需控制量少。
An electrical actuator control method based on linear quadratic regulat(LQR)control algorithm was put forword for controlling an unstable motion cycle on the two-dimensinal course correction fuze.Firstly,the electrical actuator mathematical model was written.Then,the electrical actuator mathematical model needed to be written in the form of the state space.In the next place,the model was need to determine whether it satisfied the requirement of LQR control algorithem.Finally,optimal control law followed from LQR control algorithm.Simulation results showed that,compared with the traditional three closed loop PID,this algorithm possessed short regulating time,no overshoot,high controlling accuracy and less control.
