关 键 词：Asymptotic tracking Controller parameterization H∞ performance Output weight Reduced-order controller
摘 要：This paper considers the problem of measurement output feedback H control subject to asymptotic tracking and unsatble output weights. Based on two Sylvester equations, a specifically structured controller is conducted, and the necessary and sufficient condition is given. By this parameterization, additional performance objective is further tackled via an LMI-based approach and a reduced-order controller synthesis is also discussed. An example is given to show the effectiveness of the current results.
