In this structure, the inner loop is a doubly coprime factorization disturbance observer to suppress disturbance. For non-minimum phase systems, we can find optimal solutions by solving Nehari problem and Delay-type Nehari problem. The outer loop which use Smith predictor method can reduce effect of time delays and improve servo response. A robust structure is developed to treat plant uncertain. We applied the small gain theorem to design disturbance observer that satisfies the robust stability criteria. A simple and useful parameter tuning method is proposed.
