【Abstract】 This paper studies the problem of robust controller design for systems with integral quadratic constrained uncer- tainties.By combining the method of Youla parameterization with the criterion of robust stability,the problem of robust con- troller design is converted into that of convex feasibility in RH~∞space,and is further converted into that of finding solutions for a frequency dependent linear matrix inequality.Thus,the robust controller can be achieved by the method of rational matrix in- terpolation on border.更多还原
