I are currently using "Direct Torque Control of PMSM Using Quadrature Encoder or Sensorless Flux Observer" example for high-speed PMSM motor control. The system works perfectly at 20kHz, but when I increase the PWM frequency to 40kHz, I encounter an issue with the reference speed in the host model.

For example, when I set the reference speed to 500 RPM, the host model incorrectly shows 6500 RPM. It appears that the instructed or reference speed is getting corrupted during transmission or processing. I’ve attempted various solutions, including adjusting the baud rate, hardware interrupts, and hardware initialization settings, but the issue persists.I are currently using "Direct Torque Control of PMSM Using Quadrature Encoder or Sensorless Flux Observer" example for high-speed PMSM motor control.
