To solve the presence of parameter uncertainty in strong nonlinear systems, the nonlinear predictive adaptive controller (NPAC) is presented in this paper. The controller is composed of an optimal NPAC and a nonlinear disturbance observer (NDO). NDO is used to estimate the steady-state response error, and the optimal NPAC improves the nonlinear closed-loop system stability. The simulation results from a continuous stirred tank reactor show that NPAC is effective in terms of tracking and regulation.
