摘要

This brief proposes a global nested PID control method for a class of strict feedback nonlinear systems with unknown system nonlinearities, which guarantees that the output and virtual tracking errors are confined in some prescribed performance regions and globally bounded closed loop signals. No linearized approximators are required to compensate for the unknown nonlinearities. The proposed nested PID control is capable of ensuring prescribed output and virtual tracking performance independent of control parameters and unknown system nonlinearities with low controller complexity. Finally, simulation results are given to demonstrate the effectiveness of proposed method.
