Abstract This paper presents a new approach to the automatic generation control of power systems. It makes use of the theory of variable structured systems to investigated the automatic generation control of a steam electric power plant. Improvements in both the dynamic and static performances can be achieved by means of the sliding mode provided by a variable structure controller. The main feature of the sliding mode is that the system willhave low sensitivity; certain desirable properties can be obtained by minimizing a quadratic performance index specified in the sliding mode. For comparison, results obtained using a convetional controller and a linear optimal controller are also included.
