摘要引人具有良好非线性控制能力的EMCS(Extended Minimal Control Synthesis)算法进行壁板结构振动控制。为解决控制器输出饱和问题,基于波波夫准则设计含有饱和补偿控制器的SCMCS(Saturation Compensator Minimal Control Synthesis)控制策略,并进行稳定性证明。仿真及实验结果表明,该方法在多模态正弦复合随机扰动下,较EMCS算法鲁棒稳定性更好,尤其由积分器与sign函数引起的EMCS算法控制器输出饱和现象得到有效抑制。
Extended minimal control synthesis with good ability of nonlinear control is used to suppress the panel vibration. In order to solve the problem of its controller saturation, a saturation compensator minimal control synthesis including adaptive compensation gain based on erf function is put forward. The stability of control system is verified by popov’ s criterion. Simulation and experimental results show that this method has better robustness compared with EMCS algorithm under multi-mode sine mixed broadband random disturbance. Especially the saturation caused by integrator and sign function mutation can be suppressed effectively by this method.
