Problems solved by technology

When the responsiveness is inadvertently enhanced too much, the control stability is reduced, which may reduce the responsiveness of the controller due to interference caused by external factors, friction of the mechanism, sensor noise, etc., or cause unintentional vibration

Embodiment Construction

[0033]Some exemplary embodiments may be shown in the figures in the form of functional blocks, units and / or modules, as is conventional in the respective fields. Those of ordinary skill in the art will understand that these blocks, units and / or modules are physically implemented by electronic (or optical) circuits such as logic circuits, discrete components, processors, hard-wired circuits, memory elements, wired connections, and the like. When the blocks, units and / or modules are implemented by a processor or similar hardware, they can be programmed and controlled using software (eg, code) to perform the various functions discussed herein. Alternatively, each block, unit and / or module may be implemented by or as a combination of special purpose hardware to perform some of the functions, and may be implemented by a processor (eg, one or more programmed processors and associated circuitry). Implemented to perform other functions. Each block, unit and / or module of some exemplar...

Abstract

An apparatus and method for controlling a motor-driven power steering system are disclosed. The apparatus for controlling a motor-driven power steering system includes: a steering angle position controller configured to control a steering angle by adjusting a gain value based on a steering angle error between a command steering angle input by an automatic driving system and a current steering angle; a current controller configured to compensate for a current error between a second command current output from the steering angle position controller and the sensor current; and an interference estimator configured to estimate noise due to an external factor, remove the estimated noise in advance from the third command current output by the current controller, and apply a noiseless third command current to the MDPS.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to an apparatus and method for controlling a motor-driven power steering system, and more particularly, to an apparatus and method for controlling a motor-driven power steering system capable of automatically Enhances instantaneous response when abrupt steering is required during driving, and stably maximizes performance against noise due to external factors. Background technique [0002] Generally, a hydraulic power steering apparatus using a hydraulic pressure of a hydraulic pump is used as a power assist steering apparatus for a vehicle, but since the 1990s, a motor-driven power steering (MDPS) system using an electric motor has been widely used. [0003] In the conventional hydraulic power steering apparatus, since the hydraulic pump as the power source of auxiliary power is driven by the engine, power is always consumed regardless of whether the steering wheel is turned. In an MDPS system, ho...
