摘要:

为克服大型光电跟踪平台直流调速系统的非线性因素影响,利用变结构控制响应速度快,针对系统的参数变化和外部扰动不灵敏的特点,设计了滑模变结构控制器。通过Simulink 仿真并与PID(Proportional_Integral_Differential)控制方法相比较得出,采用SMC(Sliding Mode Control)设计系统稳态跟踪的误差减小到PID控制系统的1/3,调节时间缩短为原来的1/7,由超调3%变为无超调,由对参数摄动和外部扰动敏感变为不敏感。从而证明了在大型光电跟踪平台直流调速系统中,滑模变结构控制能显著减小系统反应时间和稳态跟踪误差,对参数摄动和外部扰动具有良好的鲁棒性。

Abstract:

In order to remove the nonlinear factor of the DC(Direct Current) rotor speed regulation system in large photoelectric tracking table, a servo system with sliding mode variable structure control was designed . It achieves quick response performance and insensitivity to variation of plant parameters and external disturbance of the variable structure control. According to the simulation and relative to the PID(Proportional_Integral_Differential) controller, results show that sliding mode control can reduce adjust time and tracking error, also has a strong robustness for external disturbance and parameter change.

Key words: sliding mode variable structure control, robustness, DC rotor speed regulation system, nonlinear
