—Based on unit feedback closed-loop control structure, a simple analytical design method of decoupling controller matrix is proposed in terms of idea of coupling matrix for two-input-two-output (TITO) processes with time delays in chemical and industrial practice. By means of powerful robustness of two degree-of-freedom PID Desired Dynamic Equation (DDE)(More)
The control of Multi-tank Liquid-level System is both a typical multivariable control problem and a typical problem that is used to verify conception and method of multivariable control. In this paper, a decoupling controller matrix is designed based on the complete decoupling method of feedforward compensation. For the decoupled objective function, the(More)
Multiple-input-multiple-output (MIMO) processes with time delays commonly appear in chemical industry. Based on unity feedback closed-loop control structure, and combined with the characteristics of strong robustness of the two-degree-of-freedom (2-DOF) PID in terms of the Desired Dynamic Equation (DDE) method, a PI/PID decoupling controller was designed(More)
Multiple-input-multiple-output (MIMO) processes with time delays commonly appear in chemical and industrial practice. For MIMO processes, a PID decoupling controller is devised based on unity feedback closed-loop control structure and combined with the characteristics of strong robustness of the Desired Dynamic Equation (DDE) method for(More)
PID controller has simple structure and easy applicability with strong performance robustness. Decentralized PID controller and decoupling PID controller are widely adopted in the control of two-input-two-output (TITO) processes. Firstly, a simple decoupling controller matrix and a desired dynamic decoupling controller matrix are designed according to the(More)
