Abstract

The best phase lead is the one that can exactly compensate the phase lag of a system. A zero phase learning control using reversed time input runs is proposed, utilizing a simple phase lead generation method. The plant itself or a nominal model is used to obtain the desired phase lead. Then the results for SISO ILC system are extended to MIMO ILC system in two different ways, leading to two parallel MIMO learning control laws. These two MIMO schemes need no high order derivatives of error signals and no numerical differentiation, and thus generate little noise.
