This book explains the basic principle underlying in system/model identification.The model-based control design process involves modeling the plant to be controlled, analyzing and synthesizing a controller for the plant, simulating the plant and controller, and deploying the controller here we concentrated only on designing the controller.A comprehensive chapter which clearly explain about model structures,sugar evaporator,Fuzzy controller.A detailed work and performance analysis on sugar evaporator with conventional controllers P, PI, PID & Fuzzy logic Controller results were displayed and implemented.
