In every physically meaningful process, process variables are naturally bounded. Generally, the magnitude of a manipulated variable can only vary between the upper and lower limits of the corresponding actuator. In fact, it is questionable whether the control design procedure ignores the physical constraint of the actuator. For instance, developments in differential geometric control technique fall in the class of analytical model-based control; their approaches may reach the limit of control action so that the linearization fails and performance degradation or instability may occur. In the earlier anti-windup methods, Calvet and Arkun (1988) opted for the reconstruction of the external linear input by observing the current states as well as the original input so that the linear internal model control-based framework can enhance the regulation performance. Valluri and Soroush (1998) developed analytical nonlinear schemes that offer great flexibility to a desirable closed-loop output 1This work is partly supported by the National Science Council of Republic of China under grant number NSC-89-2214-E-224-004.

N2 - This paper deals with a catalytic continuous stirred tank reactor (CCSTR) example, mo deled as a two-input constrained nonlinear system. Based on the Lyapunov-based linearization strategy, the saturation-type parameterized control design can reduce the effect of actuator subject to amplitude and rate constraints, and the integrated two-input control framework can ensure the asymptotic output regulation and robustness against unknown disturbances. Our results are illustrated via numerical simulation.
