Virtual Reference Feedback Corrective Control Based on the Closed-Loop

Firstly two controller using the virtual reference feedback control design, at the same time considering the expectation of a given model match the closed-loop transfer function and sensitivity function, which need to be in the two objective function increases the expression in a model of the sensitivity function matching. Finally the iteration algorithm of controller parameters are obtained by mathematical method. Also the asymptotic variance matrix can be applied to the control of virtual reference feedback correction virtual signal design and controller in the process of inspection.
