Hybrid robust adaptive control for multiple-input multiple-output micro-vibration system
In recent years,Q parameterization method has reflected significant advantages in the application of vibration adaptive control.For the multiple input multiple output(MIMO)active vibration control system,a MIMO hybrid robust adaptive vibration control method based unlimited pulse response infinite impulse response(IIR)filter is presented in this paper.This hybrid control method takes advantage of the Q parametrization of the feedback controller and feedforward controller.The deducing process of the feedforward MIMO robust adaptive control method and feedback MIMO robust adaptive control method are illustrated in detail.And based the deducing process of hybrid MIMO robust adaptive control method,it's stability and convergence are analyzed.A 3-degree of freedom real time micro-vibration control experimental platform is constructed.Comparison with sine disturbance and double sine disturbance are provided.Experimental results confirm the feasibility and effectiveness of the proposed algorithm.
