An actuator control device comprising: a control circuit for controlling an actuator by using at least one of a first assist component (Ta1*) and a second assist component (Ta2*) such that the actuator generates a force that causes a steering operation mechanism of a vehicle to steer a steered wheel, the first assist component (Ta1*) being calculated on a basis of an operational state amount changing in accordance with an operation applied by a user to the steering operation mechanism, the second assist component (Ta2*) being calculated on a basis of an environment surrounding the vehicle, wherein the control circuit is allowed to calculate the first assist component (Ta1*) while the operational state amount is not less than a first threshold value, and is allowed to calculate the second assist component (Ta2*) while the operational state amount is less than the first threshold value, the control circuit calculates the second assist component (Ta2*) by performing feedback control that uses a control term including at least an integral term that is obtained on a basis of a deviation between target and actual values of a directional state amount that is a component indicative of a direction of travel of the vehicle, the target value of the directional state amount being set on a basis of the environment surrounding the vehicle, and when the operational state amount is less than the first threshold value but not less than a second threshold value that is less than the first threshold value, the control circuit performs a limitation process that limits the control term used in the feedback control in such a manner that it is harder for the control term to increase while the operational state amount is not less than the second threshold value than while the operational state amount is less than the second threshold value, wherein the control term used in the feedback control performed by the control circuit includes a proportional term, an integral term, and a derivative term, the proportional term being obtained on a basis of the deviation between the target and actual values of the directional state amount, the integral term being obtained by accumulating an integral element based on the deviation, the derivative term being obtained on a basis of a derivative element based on the deviation, characterized in that, the limitation process limits at least the integral term, out of the control term. a control circuit for controlling an actuator by using at least one of a first assist component (Ta1*) and a second assist component (Ta2*) such that the actuator generates a force that causes a steering operation mechanism of a vehicle to steer a steered wheel, the first assist component (Ta1*) being calculated on a basis of an operational state amount changing in accordance with an operation applied by a user to the steering operation mechanism, the second assist component (Ta2*) being calculated on a basis of an environment surrounding the vehicle, wherein the control circuit is allowed to calculate the first assist component (Ta1*) while the operational state amount is not less than a first threshold value, and is allowed to calculate the second assist component (Ta2*) while the operational state amount is less than the first threshold value, the control circuit calculates the second assist component (Ta2*) by performing feedback control that uses a control term including at least an integral term that is obtained on a basis of a deviation between target and actual values of a directional state amount that is a component indicative of a direction of travel of the vehicle, the target value of the directional state amount being set on a basis of the environment surrounding the vehicle, and when the operational state amount is less than the first threshold value but not less than a second threshold value that is less than the first threshold value, the control circuit performs a limitation process that limits the control term used in the feedback control in such a manner that it is harder for the control term to increase while the operational state amount is not less than the second threshold value than while the operational state amount is less than the second threshold value, wherein the control term used in the feedback control performed by the control circuit includes a proportional term, an integral term, and a derivative term, the proportional term being obtained on a basis of the deviation between the target and actual values of the directional state amount, the integral term being obtained by accumulating an integral element based on the deviation, the derivative term being obtained on a basis of a derivative element based on the deviation, characterized in that, the limitation process limits at least the integral term, out of the control term.
