Robust Adaptive Control of A Disturbed Chua’s Circuit with Circuit Implementation

In this paper, a circuit implementation scheme is designed for the adaptive algorithm applied to the disturbed Chua’s circuit system. Firstly, in order to effectively suppress the adverse effects of unknown disturbances on the system, the input of the system is designed by using the method of adaptive parameter adjustment. Then, the asymptotic stability of the ADRC system is proved by lyapunov theorem. Besides, the pure circuit implementation scheme of the control algorithm is given by using the combination of some basic analog components. Finally, the software Multisim is used to do the circuit simulation experiments, and the experiment results show that the circuit design scheme of the algorithm is correct.
