Decentralized Compensated Active Disturbance Rejection Control Method and Frequency Domain Analysis for Multivariable Systems
摘要
Abstract
To control multivariable objects with high-order large inertia in a thermal system using a low-order controller,we propose a decentralized compensated active disturbance rejection control meth-od by combining high-order compensation control and decentralized active disturbance rejection control.Consequently,we theoretically derive the closed-loop transfer function of the system.Using the inverse Nyquist array design method in the multivariable system,we quantitatively ana-lyze the stability region size of the proposed decentralized compensated active disturbance rejection control and the conventional decentralized control method.The simulation results show that the de-centralized compensated active disturbance rejection control is superior to the conventional decen-tralized active disturbance rejection control without compensation in terms of stability region size,dynamic performance,and robustness.It improves the control performance of a high-order multiva-riable system controlled by a low-order controller and has good application prospects.关键词
