This paper presents the design and implementation of model reference adaptive control (MRAC) on temperature regulation of glycerin bleaching process. The established first order MRAC design based on Lyapunov approach is considered. For developing robust MRAC performance, simple modification has been made by removing the integral term on the adaptation rule of MRAC in order to prevent the controller from windup phenomenon. The performance analysis of the controller was carried out using standard transient analysis with 2% band, while mean square error (MSE) is used for steady state analysis. Initially, the performance of MRAC without integral was analyzed via simulation scheme and followed by real time implementation afterward. Both of the results, from the simulation and real time execution, indicate the effectiveness of this modification towards the performance of MRAC. Also, it offers robust performance throughout temperature regulation of glycerin bleaching process. A comparative study with real time performance of PID with back calculation anti windup controller denote that MRAC without integral is capable to provide better performance on regulating temperature of glycerin bleaching process. © 2006-2015 Asian Research Publishing Network (ARPN).
