摘要： An electric power steering system is provided which is capable of providing a favorable steering feeling without using compensation logics such as of inertia compensation and friction compensation. The electric power steering system includes road-noise suppression control means (213) for controlling a steering assist motor (9) in a manner to damp torque transmission in a higher frequency region representing road noises than a frequency region representing road information. A friction value of a steering mechanism (A) is decreased enough to allow the intrinsic vibrations of the steering mechanism (A) to appear. Rotor inertia of the steering assist motor (9) is set to a value small enough to allow the frequencies of the intrinsic vibrations to be present in the frequency region where the torque transmission is damped by the road-noise suppression control means (213).

摘要： A controller for a machine capable of performing acceleration/deceleration control to which an optimal tangential acceleration within an allowable maximum acceleration for each axis is applied. A first interpolation section receives data obtained by analysis of a program by a command analysis section, an makes interpolating calculation in every first sampling period to output it into an intermediate memory. A tangential acceleration calculating section determines a tangential acceleration based on each segment and the allowable maximum acceleration for each axis to output it into the intermediate memory. A deceleration target velocity calculating section prepares an acceleration/deceleration pattern for a plurality of segments stored in the intermediate memory, to output it to the intermediate memory. An acceleration/deceleration control section performs acceleration/deceleration control based on the data in the intermediate memory so that the tangential velocity at an end point of each segment is not higher than the deceleration target velocity, and calculates velocity for each second sampling period. A second interpolation section defines a smooth curve based on the output from the acceleration/deceleration control section and the data taken out from the intermediate memory, and outputs a point on the smooth curve for each second sampling period.
