PROBLEM TO BE SOLVED: To exclude any constraint on the responding performance of each control system, to clarify a physical phenomenal relation between each controller and the state variable of an object to be controlled, and to simplify adjustment by applying a prescribed response function previously decided by a designer for plural control systems to the object to be controlled, and designing a controller in each control system. SOLUTION: This is a controller for deciding the control arithmetic function of a controller from a transfer function 1 of an object to be controlled, and adjusting the manipulated variable of the object to be controlled according to the decided control arithmetic function. In this case, the control arithmetic function of a first controller 2 is decided so that a closed loop/open loop transfer function or a closed loop transfer function in a control system including the object to be controlled and the first controller 2 can be made coincident with a previously decided first transfer function, and the control arithmetic function of a second controller 3 is decided so that a transfer function up to a state variable at a point at which disturbance is impressed to the object to be controlled can be made coincident with a previously decided second transfer function for a closed loop control system constituted of the controller and the first controller 2. Then, the sum signal of the outputs of the first and second controllers 2 and 3 can be obtained as the manipulated variable of the object to be controlled. |
