A New Robust Controller Design Method for Distributed Parameter Systems Abstract: We consider robust stabilization of linear time-invariant multi-input-multi-output (MIMO) infinite-dimensional systems (with finitely many unstable poles) whose transfer functions are factorized in a special form. Important practical applications include finite-dimensional MIMO systems with time delays in the output channels. The controllers are designed from […]
