Abstract

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.
