Abstract : "This paper deals with design of integer and non-integer IMC based controllers for automatic generation control of two area power system using the simplified decoupling technique. A two area non-reheated interconnected thermal power system is considered for decentralised controller design. The coupling among areas are the main hurdle encountered in the design of controller. Hence, the idea of simplified decoupling technique is introduced to decouple the two area power system into two equivalent independent SISO systems. Integer and non-integer internal model control (IMC), are independently designed for each area based on decoupled systems. The performance of two area power system equipped with proposed controller is analysed through MATLAB. Simulation results show that proposed controller maintains robust performance and can minimize the load fluctuations. Finally, the method is extended to three area power system.ptive Fuzzy Observer is firstly proposed to achieve a simultaneous estimation of descriptor system states, actuator"
