- BLDC모터 속도응답 특성 개선을 위한 퍼지 PID 제어 알고리즘
While today's BLDC motors are high performance and small in size, they are widely used for industrial use due to their small and efficient torque, and a variety of control techniques are being developed to achieve optimum performance. A typical PI controller is often used to control such BLDC motors However, PI control has a large overshoot and the setting time is longer when switching speeds. Although many PID controllers are used to address this, it takes a lot of experience and effort to achieve optimized benefits. To address this problem, we propose a fuzzy PID control algorithm, a combination of fuzzy control controllers and PID controllers that have a short time of reaching normal state from transient response state without a large overshoot. The test results showed that speed control reached normal state 0.014 seconds faster than the existing PID control.
