摘要:
针对反作用飞轮大惯量、受多种干扰力矩综合作用的特点和采用传统控制方法很难满足其动态品质和扰动抑制能力要求的问题,对卫星高精度姿态控制系统中的磁悬浮反作用飞轮电机进行系统分析与建模,并依据变结构控制理论提出一种双滑模面变结构控制方法,控制器的设计满足以李导数形式表达的到达条件。仿真结果表明:与经典PID控制器相比双滑模面变结构控制器具有超调量、稳态误差小,响应速度快、扰动抑制能力强的优点;与单滑模面变结构控制器相比双滑模面变结构控制器有效的抑制了滑模抖振,减小了系统的超条量和稳态误差。双滑模面变结构控制提高了磁悬浮反作用飞轮电机的动态性能和控制系统的抗干扰能力,对于实现卫星高精度、高稳定度控制具有重要意义。
Abstract:
Aiming at the characteristics and the request of reaction flywheel, a twoloop variable structure control method was designed according to the variable structure control theory. It was based on the system analyzing and modeling on brushless DC motor (BLDCM) of Magnetically Suspended Reaction Flywheel (MSRW). The design of the controller satisfies reach qualification. The simulation results prove that the new control method has the advantages of improving system dynamic response, reducing steadystate error and invariance to the disturbances compared with the PID controller, chattering and reducing steadystate error compared with the singleloop variable structure control method. This control method improves MSRW control system’s dynamic response and disturbancerejection ability, which is important for realizing the high precision and high steady satellite attitude control.
