A polynomial-based approach to design controllers of non-minimum phase nonlinear systems

In this paper we developed a control approach of nonlinear systems with non-minimum phase. The proposed approach is based on the exact input-output linearization and the Lyapunov theory. The main contribution in this work is to solve the problem of the instable internal dynamics. An application of the obtained nonlinear control law to the chemical reactor system stabilization gives very interesting results. Numerical Simulations are presented to illustrate the efficiency of the proposed scheme.
