Abstract: | The paper deals with continuous-time adaptive control of a continuous stirred tank reactor (CSTR). A nonlinear model of the plant is approximated by an external linear model with recursively estimated parameters. Both, one degree of freedom (1DOF) and two degrees of freedom (2DOF) control system configurations are considered. Resulting controllers ensure internal properness and stability of the control system as well as asymptotic tracking of the step reference and step load disturbance attenuation. The design procedure is based on the polynomial method. An application of the LQ control technique yields a control law penalising the control input changes. The adaptive control is tested by simulation means. | ||||||||||
