Envelope-constrained H/sub ∞/ filter design: An LMI optimization approach

In this correspondence, we solve the envelope-constrained H/sub /spl infin// filter design problem by minimizing the H/sub /spl infin// norm of the filtering error transfer function subject to the constraint that the filter output is contained in a prescribed envelope. The filter design is transformed into a standard linear matrix inequality (LMI) optimization problem.
