Claim 0:
1. A turning control system for operating a turning actuator that includes an electric motor incorporated therein and turns turning wheels, the turning control system comprising:
a processor configured to:
calculate a steering operation amount, which is convertible to a torque required for the electric motor for turning the turning wheels, to convert a steering torque input by a driver to a target steering torque by feedback control;
calculate an angle command value of a convertible angle which is convertible to a turning angle of the turning wheels based on the steering operation amount;
calculate an angle operation amount, which is convertible to the torque required for the electric motor, for converting the convertible angle to the angle command value by feedback control;
operate a drive circuit of the electric motor to control torque of the electric motor;
adjust a magnitude of a control value which is subtracted from the angle operation amount and input the angle operation amount with the control value subtracted to operate the drive circuit of the electric motor; and
in response to the angle command value being calculated, correct a magnitude of an input to be less given that the magnitude of the control value is a first value, as compared to a case where the magnitude of the control value is a second value smaller than the first value, using a normative model.
