This paper presents a method to compensate the effect of non-cancellable zeros of the plant on output by incorporating finite impulse response (FIR) filter in the feed-forward path. This FIR filter is designed using the approximate inverse system of the non-cancellable part of numerator polynomial of the plant. The proposed controller guarantees boundedness of all signals from the reference input to the plant output. Computer simulation and real-time control experiment results are given to demonstrate the effectiveness of the proposed method.
