Background and Introduction:
The proposed control law is designed to provide fast reference
tracking with minimal overshoot and to minimize the effect of unknown nonlinearities and
external disturbances.
Methods:
In this work, an enhanced composite nonlinear feedback technique using adaptive control
is developed for a nonlinear delayed system subjected to input saturation and exogenous disturbances.
It ensures that the plant response is not affected by adverse effect of actuator saturation, unknown
time delay and unknown nonlinearities/ disturbances. The analysis of stability is done by
Lyapunov-Krasovskii functional that guarantees asymptotical stability.
Results:
The proposed control law is validated by its implementation on exothermic chemical reactor.
MATLAB figures are provided to compare the results.
Conclusion:
The simulation results of the proposed controller are compared with the conventional
composite nonlinear feedback control which illustrates the efficiency of the proposed controller.
