摘要
以三轴飞行转台内框伺服控制系统为研究对象,提出了常规PID控制算法和基于模型预测的BP神经网络PID控制算法,并对阶跃、斜坡、加速度输入信号进行MATLAB仿真,得出误差曲线.仿真结果对比表明,在控制对象不确定的情况下,后者是较优越的一种算法,对改进转台控制效果有着较大的参考意义.
With its research focus on the servo control system of three-axis flying simulators, this paper puts forward the traditional PID control arithmetic and NN PID control way arithmetic based on model forecast. MATLAB simulation is conducted to test stepping, slop, and acceleration input signals. The result shows that NN PID control way arithmetic is better provided the control object is uncertain. It is also very important to enhance the efficiency of flying simulator control.
