Abstract :
A class of nonlinear system is substituted by a time-varying linear system. Cubic spline functions are used directly to identify the coefficients of time-varying linear system. Then minimum variance controller for the nonlinear system is designed. The stability of closed-loop system is proved. The effectiveness of the presented method is demonstrated by the simulation results.
