    Abstract: The present invention provides a controller for controlling a modeled plant robustly against disturbance. The controller comprises an estimator and a control unit. The estimator estimates disturbance applied to the plant. The control unit determines an input to the plant so that an output of the plant converges to a desired value. The input to the plant is determined to include a value obtained by multiplying the estimated disturbance by a predetermined gain. Since estimated disturbance is reflected in the input to the plant, control having robustness against disturbance is implemented. The controller may comprise a state predictor. The state predictor predicts the output of the plant based on the estimated disturbance and dead time included in the plant. The control unit determined the input to the plant so that the predicted output converges to a desired value. Since the state predictor allows for the dead time, the accuracy of the control is improved. The estimated disturbance is reflected in the predicted output, an error between the predicted output and an actual output of the plant is removed.

    Abstract: A controller for a contact mechanism for preventing a lack of a pressing force applied from a contacting member to a contacted member when determining a control input to an actuator moving the contacting member by a position control. The controller sets a target position of the contacting member, grasps an actual position of the contacting member, determines a control input to the actuator (so as to increase an output of the actuator along with an increase in a difference between the target position and the actual position of the contacting member to eliminate the difference), and detects that the contacting member contacts the contacted member.

    Abstract: A controller for a plant that can compensate for non-linear property and reduce oscillation of output of a controlled object even when the controlled object has high non-linear property is provided. The present invention provides a controller for a plant that uses PWM algorithm. The device calculates provisional control input for controlling output of the plant at a target value, and divides the provisional control input into a plurality of components. The controller PWM-modulates at least one of the plurality of components, and sums the PWM-modulated component and other components to produce a control input to the plant. The controller minimizes variations in input while maintaining the ability of PWM modulation to compensate for non-linear property of the plant.

    Abstract: The present invention provides a control apparatus for a plant, which can suppress excessive correction for a spiky disturbance being applied and maintain a good controllability, when controlling the plant, which is a controlled object, with the self-tuning regulator. A detected equivalent ratio KACT is input to a high-pass filter 33, and a high-pass filter output KACTHP is input to a parameter adjusting mechanism 42. The parameter adjusting mechanism 42 calculates a corrected updating vector (KID·dθ(k)) by multiplying an updating component dθ of a model parameter vector by a correction coefficient KID, and adds the corrected updating vector to a preceding value θ(k−1) of the model parameter vector, to thereby calculate a present value θ(k). The correction coefficient KID is changed from “1.0” to a value near “0” upon detection of the spiky response where an absolute value of the high-pass filter output KACTHP increases.
