Abstract

Disturbance estimator estimates, based on a first manipulative variable and a controlled variable, a disturbance for a control target which outputs a controlled variable according to first manipulative variable, and outputs an estimation signal including an amount of disturbance. Model predictive controller calculates a second manipulative variable based on controlled variable to output a control signal including second manipulative variable. Modifier modifies second manipulative variable by reference to modification information based on amount of disturbance and thereby provides output signal including first manipulative variable as second manipulative variable thus modified. Model predictive controller includes one or more first processors. Disturbance estimator includes one or more second processors. Model predictive controller outputs control signal in a first output cycle. Disturbance estimator outputs estimation signal in a second output cycle. Modifier provides output signal in a third output cycle. Second and third output cycles are both shorter than first output cycle.

Dependent claims

A control system configured to provide an output signal including a first manipulative variable to a control target, the control system comprising:

a disturbance estimator configured to estimate, based on the first manipulative variable and a controlled variable, a disturbance generated by, or applied to, the control target and output, as a result of estimation, an estimation signal including an amount of disturbance, the control target outputting a controlled variable signal including the controlled variable according to the first manipulative variable;
a model predictive controller configured to calculate a second manipulative variable based on the controlled variable to output a control signal including the second manipulative variable;
and
a modifier configured to modify the second manipulative variable by reference to modification information based on the amount of disturbance and thereby provide the output signal including the first manipulative variable as the second manipulative variable thus modified,
the model predictive controller including one or more first processors configured to perform processing on model predictive control,
the disturbance estimator including one or more second processors configured to perform processing on disturbance estimation,
the model predictive controller being configured to output the control signal in a first output cycle,
the disturbance estimator being configured to output the estimation signal in a second output cycle,
the modifier being configured to provide the output signal in a third output cycle, and
the second output cycle and the third output cycle being both shorter than the first output cycle.
