    • PURPOSE:To minimize the control time by selecting the control gain of the shortest time in order to eliminate the deviation caused between a controlled variable and the target value within an input limit range in sampling and then generating an input to be applied a control subject. CONSTITUTION:When the initial value of a state variable of the position, the velocity, etc., is given to a control subject 11 having the limitation of input, an arithmetic means 12 calculates (m) pieces of control gain Fc in order to set the state value at '0' in (m) hours from the present point. Then a controller 13 selects one of these gains Fc so as to set the deviation et caused between a controlled variable Xt calculated by an adder 14 within an input limit range and the target value Xd at '0' the shortest time. An input Ut is obtained from the gain Fc and the deviation et and inputted to the subject 11. Thus it is possible to obtain a controller that can produce an input coincident with the value Xd in the shortest time.

    • PURPOSE:To obtain a satisfactory response even when a dynamic characteristic of a kinetic machine system being a control object by generating a control input for shifting a deviation between a controlled variable and a target value to a stable phase face in accordance with a non-linear control law. CONSTITUTION:By an arithmetic means 12, a deviation (s) from a designated stable phase face is operated from a deviation (e) between a controlled variable (x) of a control object and a target value (r), and in an adaptive means 13, a parameter thetaof the control object is identified so that the deviation (e) between the controlled variable (x) of the control object and the target value (r) becomes minimum by using a result of its operation. In a controller 14, a control input tau is generated so as to shift the deviation (e) between the target value (r) and the controlled variable (x) to a designated stable phase face by a non-linear control law by using the deviation (s) obtained by the arithmetic means 12 and the parameter theta identified by the adaptive means 13. The non-linear control law used in this case has an integral function for setting the deviation (e) between the controlled variable (x) in a stationary state and the target value (r) to '0'. In such a way, even when a dynamic characteristic of a kinetic machine system being the control object is varied, and error is compensated and a stable response is obtained.

    • PURPOSE:To improve the responsiveness by defining the output, which is obtained by integrating the operation quantity obtained from the difference between a target value and a control quantity, as an operation quantity in case that plural measured quantities including plural control quantities are fluctuated by any of plural operation quantities. CONSTITUTION:In case that plural control quantities, for example, temperatures Y1-Y5 of respective parts of an enameled wire baking furnace 30 are fluctuated by any of plural operation quantities (opening quantities of a damper) U1-U5, differences epsilon1-epsilon4 between these control quantities and control target values YR1-YR4 are obtained. These differences are inputted to an operating element C to obtain operation variables U'C1-U'C5', and variables UC1-UC5 are obtained by integrators I1-I5 and are added to operation quantities U1-U5 respectively through a limiter L. Feedback quantities UF1-UF5 are obtained through a feedback element F from points 31, and feed-forward quantities UN1-UN5 are obtained through a feed-forward element N from points 34, and they are operated in a part 33. Thus, a control having the excellent responsiveness is possible. This system is suitable for the temperature control of the enameled wire baking furnace.
