Every process is needed to control to get the desired outcome from the process. The control action over the process parameters is so called process control. Adaptive control is the control method used by a controller which must adapt to a controlled system with parameters which vary, or are initially uncertain. In this work, an adaptive control design for a linear PI controller is attempted. Continuous Stirred Tank Reactor (CSTR) plays an important role in the processing industries. It helps for maintaining the temperature of the liquid in the reactors. In this work a CSTR process is modeled in nonlinear differential equation form and also linearized plant model form. Then, the plant is controlled by designing and implementing a conventional PI controller, Multi-model PI controller and an Adaptive PI controller. The performances of the process with conventional PI controller and the adaptive controller are analyzed from the responses, to show that the Adaptive PI controller outperforms the linear PI controller. Also the adaptive PI controller meets with the desired performance criteria. A simulation is made using MATLAB and the results were analyzed. Hence it proves that the response of adaptive PI control is better than the other PI controlled control system. Thus the designed Adaptive PI controller is suitable to control the CSTR process.
