The reference trajectory of common model control (CMC) scheme is a classic second order curve. The parameters of CMC are of very explicit physic meaning and it is very easy to tune for the controller. Combining the CMC algorithm with the nonlinear observer to estimate the parameters of the controller on line, an adaptive nonlinear control scheme is developed. The parameters of the adaptive control scheme are of very explicit physic meaning and it is very easy to tune for the controller and the nonlinear observer. The simulation results for a nonlinear pressure tank show that the adaptive common model controller is very effective for nonlinear systems.
