The chattering of the VSC system is effectively minimised by designing a load thrust observer and a disturbance feed forward compensation.
负载推力观测器和扰动前馈补偿的设计有效地削弱了变结构控制产生的抖振。

Besides, feedback compensation is used to compensate the irregular disturbance in the system.
同时，针对空调系统中可能出现较大非规律性扰动，采取了反馈补偿的措施。
3
System performance is influenced seriously by the phase disturbance caused by atmospheric turbulence and the problem may be solved by using the adaptive optics compensation.
