摘要
提出了一种实现系统干扰补偿的控制策略。针对无界斜坡干扰情况 ,通过构造一个系统输出并为其设计观测器 ,实现了对状态和干扰的同时估计 ,并将干扰的估计量引入到控制律当中 ,从而实现系统对干扰的补偿控制。仿真结果验证了这一方法的有效性。
A control strategy is proposed to compensate the effect of the external step or ramp disturbance on the system. By constructing an output of system and designing an observer for the fictitious output , both system states and disturbance can be estimated simultaneously. Then the estimation of disturbance is applied to the control law, which guarantees the desired performance of the system and compensates the disturbance. At last, simulation result demonstrates the proposed method.
