Title: Position Control of Electro-mechanical Fin Actuator using Linear Type Hall-effect Sensor BLDC Motor with Magnetic Flux Shielding Wall
Abstract: In general, position sensor and velocity sensor are used to design robust controller of the electro-mechanical fin actuator system. However, the use of such a sensor causes problems such as an increase in cost, an additional space for mounting, and a decrease in system reliability due to a sensor failure. To overcome these problems, rotor position sensor of the BLDC motor was replaced with linear type Hall-effect sensor having a magnetic flux shielding wall from the latch type Hall-effect sensor. The conventional position sensor and velocity sensor were removed through a position and velocity implementation algorithm using the analog output of the linear type Hall-effect sensor. In order to prove the validity of the proposed method, various comparison tests were performed with the existing position/velocity sensors. As a result of the test, the method proposed in this paper can obtain the position response similar to the case of applying the conventional position/velocity sensor.
