摘　　要：针对某卫星发射场活动勤务塔电气传动控制系统非线性、时变、难以精确建模等问题,提出一种时间最优参数自调整模糊控制方法.该方法采用Bang-Bang控制改善系统动态性能,用参数自调整的自适应解析模糊控制改善系统稳态性能,实现高精度控制.由于在控制过程中的不同阶段采用不同的控制方式,既继承了Bang-Bang控制动态性能好,同时又具有无静差的优点.仿真实验表明,该控制系统动态性好、稳态精度高,且鲁棒性好,能满足电气传动控制系统的要求.To a series of problems,such as nonlinearities,time variations and the difficulties in getting mathematic models,for the complicated characteristics of electric drive controlling system in the mobile service tower at a certain satellite launching base,the superior time and parameters-adjustable fuzzy logic control strategy is proposed.The dynamic characteristic of electric drive controlling system is enhanced by using Bang-Bang control.The adaptive analytical fuzzy logic control strategy with adjusted parameters is used in the controlling process.As a result,the static performance is improved,which realizes the high accuracy control.Because different control schemes are used in different methods of the whole control process,the controller keeps good dynamic performance of Bang-Bang control,and has the merit of non-static errors.The simulation result shows that the system has good dynamic and static performance,and the robustness is good as well,which can satisfy the request of electric drive control system.
