Research on the Energy Error Control Algorithm Based on the Differential Equation Model

摘要

According to the torque balance principle and circuit analysis theory, this study established the model that motor driving current relying on observable rotate speed and torque. The classical computer control method in which current relying on rotate speed difference can?t properly calculate the current value, the differential calculation of rotate speed make the circuit into a feedback system, the performance is unstable. Through the differential equation model, this study redesigned the control algorithm to calculate the motor?s parameter and then using the rotate speed and torque which can be observed to make the transformation of variables. Finally, the experiment shows that this energy error control algorithm can well make real-time control of current value.
