    • There is provided a control system for an electronic power steering. The control system includes: a SAT estimating portion for estimating a self aligning torque (SAT) of a vehicle by inputting an angular velocity and an angular acceleration of a motor, a steering torque, and a current command value; and a motor current correction value calculating portion for deciding a running state of the vehicle based on a SAT estimation value estimated by the SAT estimating portion, a vehicle speed, and a steering angle, and correcting the current command value by calculating a motor current correction value based on the SAT estimation value in accordance with the running state. According to this configuration, an offset torque can be always corrected precisely irrespective of a road surface situation or a driving condition such as a straight line running, and thus a comfortable steering performance can be attained by lessening driver's fatigue.

    • This converter for electrical power recovery (1) for supplying power to a load (6) includes an in-house power generation device (5) for supplying power in cooperation with input terminal power at a power input terminal (2). Moreover, it includes a thermal storage unit (12) which, when surplus power is generated in a state in which a target value for input terminal power is set to zero, thermally stores this power. Furthermore, a control unit (9) is included which, when surplus power is generated, decides whether or not breakage of a wire of a CT (7) has occurred by raising the target value for the input terminal power from zero to a predetermined value, and by deciding whether or not the power input terminal current is somewhat elevated from zero.
