摘要
在位置伺服控制系统中,古典频域校正方法虽可有效地针对系统频响要求进行控制器设计,但各种干扰力矩的存在,严重影响了系统的性能。依据原有的频域校正控制器导出滑模切换面,给出了满足系统频响要求的滑模补偿器设计方法,在有效地克服干扰力矩影响的同时,又保证了系统动态频响性能,并已成功应用于某型飞行仿真转台的控制系统中。
For position-servo systems, the classical frequency-domain compensation can effectively provide controller design according to the requirements Of frequency responses, but the performance is seriously influenced by all kinds of disturbance torques. A novel sliding mode compensator is derived based on the classical frequency-domain compensation, which can overcome the influence of disturbance torques effectively while the frequency-domain performance is retained. The proposed compensator has been applied to a flight simulation turning table control with satisfactory results obtained.
