In this solution, a time-delay unit is added before the conventional reduced-order extended-state observer. For the fair comparison of the proposed ADRC and the conventional PID controller, parameters of each algorithm are obtained by using the mutative-scale chaotic optimization method. Simulation results show that the optimized ADRC not only has better decoupling performance, but also provides higher robustness and adaptability against the model-parameter uncertainties and external disturbances. %K multivariable systems %K dynamic decoupling %K active disturbance rejection control %K delay systems %K uncertain systems
