Abstract

This study proposes a controller that compensates torque error for precise angular velocity tracking and a method to compensate the stability of controller in implementation. Also, it is proved that the designed controller can be asymptotically stable based on Lyapunov stability theory. The proposed controller is able to control the d-axis reference current to arbitrary values and easily achieve control performance with two gains. As a result of applying to IPMSM of about 750W class, the steady state error with reference speed 1200 [RPM] is within 0.1 [%]. And it can be seen that it is an asymptomatic stable controller overcoming disturbance within about 0.2 second in application of constant load of about 5 [Nm].

본 연구는 정밀한 각속도 추종을 위해 토크오차를 보상하는 제어기와 구현에서 제어기의 안정성을 보완하는 방법을 제안한다. 또한 설계된 제어기가 점근적인 안정할 수 있음을 리아프노프 안정도이론에 근거하여 증명하였다. 제안된 제어기는 d축 기준전류를 임의 값에 대한 제어가 가능하고, 속도이득과 전류이득의 두 가지로 손쉽게 제어성능을 달성할 수 있도록 하였다. 약 750W급의 IPMSM에 적용한 결과 레퍼런스 속도 1200[RPM]에 대한 정상상태 오차는 0.1[%]이내이며, 약 5[Nm]의 상수부하에서 약 0.2초 이내에 외란을 극복하여 점근적인 안정한 제어기임을 확인 할 수 있다.
