摘要
为了解决光电伺服平台中的输入饱和问题,采用了基于过渡过程的滑模控制算法。过渡过程算法是基于时间最优理论设计的,将跳变的输入信号变为一个缓慢上升的信号,使系统的初始跟踪误差减小,从而避免了输入饱和现象,提高了系统的稳定性。结果表明,该方法可以有效消除输入饱和现象,适用于光电伺服平台的目标跟踪,具有重要研究与应用价值。
In order to solve the input saturation problem in the optoelectronic servo platform,a sliding mode control algorithm based on the transition process is adopted.The transition process algorithm is designed based on the time-optimal theory,which makes the hopping input signal become a slowly rising signal,so that the initial tracking error of the system is decrease,thus avoiding the input saturation phenomenon and greatly improving the system stability.After theoretical analysis and experimental verification,the results show that the proposed method can effectively eliminate the input saturation phenomenon and is suitable for target tracking of the optoelectronic servo platform and has important research and application value.
