An Experimental Comparative Study of Modified Smith Predictor Based Fractional Order Controller Design Strategies for a Time Delay Process

This paper presents real-time applications of various modified Smith Predictor (SP) based fractional order controller design strategies in control a time-delay thermal process. The elaborated methods and tuning strategies are selected carefully. A comprehensive performance evaluation is illustrated through a set of performance metrics. Further, complementary comments are highlighted on the advantages and drawbacks of each control scheme.
