Embodiment Construction
[0028] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0029] The invention is in figure 1 The shown model reference adaptive observer-based permanent magnet synchronous motor speed control system is implemented. The system includes two current loop PI controllers (PI1, PI2), speed loop PI controller (PI3), and IPARK transformation module , SVPWM modulation module, inverter bridge circuit, permanent magnet synchronous motor body, CLARK transformation module, PARK transformation module and a model reference adaptive observer module based on a superhelical sliding mode, and the model reference adaptive observer module based on a superhelical sliding mode The input terminal of the observer module is connected to the two output terminals of the PARK transformation module and the output terminals of the two current loop PI controllers (PI1 and PI2). The model based on the superhelical sliding mode refer...
