A model following control system for setting desirable characteristics of a plant using fuzzy sets is disclosed. An output from the reference model (2) is obtained for given input data. A difference between the output data of a plant (6) and the output data of the reference model (2) is input to a first high gain element (1). An output data of the first high gain element (1) is input to the reference model (2). A difference between the output data of the first high gain element (1) and a command data which is the target (R) is input as the input data to a second high gain element (5) and the plant (6) is controlled using the output data of the second high gain element (5).
