ABSTRACT:
An actuator for effecting a steering action is controlled by a feed-forward variable based on a target steering angle, a state feedback control variable based on an actual steering angle, and an integral control variable given as a sum of an integrated value of a deviation between the target steering angle and the actual steering angle, and an integrated value cancelling variable based on the target steering angle. The integral control variable is disregarded when the detected load is greater than the threshold value. Typically, the integrated value cancelling variable consists of a feedback state variable based on the actual steering angle. Thus, by disregarding the integral control variable in a low speed condition that involves a high load condition but does not require a high tracking capability, the need for the output capacity of the actuator can be substantially reduced without creating substantially any ill effect. This is particularly advantageous when applied to a rear wheel steering system of a front and rear wheel steering vehicle using an electric motor for its actuator.
