Abstract

This paper has implemented an adaptive control technique for Continuous Stirred Tank Reactor (CSTR) process. The transfer function representing the dynamics of a CSTR process was obtained. The system was modeled in Simulink and simulated without being compensated. The output response in terms of concentration to unit step input revealed that a compensator was needed to improve the transient characteristics performance. A Model Reference Adaptive Controller (MRAC) was designed based on the MIT rule and integrated with CSTR process. The Simulink model of the MRAC control for CSTR process is developed. The performance of the MRAC controller was analyzed in terms of Integral Square Error (ISE), Integral Absolute Error (IAE) and Integral Time Absolute Error (ITAE). The simulation results obtained showed that the controller provided robust and improved tracking error for the range of gain selected, with gain adjusted to 25 providing the most effective and robust tracking error performance with ISE of 0.3324, IAE of 0.4408, and ITAE of 0.3945.
