Abstract: | This paper prDposes a decoupling control scheme with two-degrees-of-freedom (2DOF) control structure.In the propased scheme,two multivariable controllers are designed based on Internal Model Control (IMC) theory for setpoint tracking and disturbance rejection independently.An aaalytical approximation method is utilized to reduce the order of the controllers.By adjusting the correspanding controller parameter,the setpoint tracking and disturbance rejection of each control loop can be tuned independently.In the presence of multiplicative input uncertainty,a calculation methed is also proposed to derive the low bounds of the control parameters in order to guarantee the robust stability of the system.Simulations arc illustrated to demonstrate the validity of the proposed control scheme. |
