Hi,

It seems InstaSpin FOC is using a single parameter tuning algorithm called Active Disturbance Rejection Control.

But, the simulations in VisSim still seem to be using a PI control. So, what exactly is being used?

Also, is it non-linear ADRC or a linear ADRC (LADRC) implementation?

Which one is better in terms of performance and MCU implementation run time.

Hi Rushi,

The single parameter tuning speed controller is available in InstaSPIN-MOTION. It is a patented ADRC implementation (SpinTAC) and is running off secured ROM on TMS320F28069M. Simulation for SpinTAC is not available in VisSim or MATLAB. Thanks.

Hi Han,

Thanks for the reply. Can you let me know what is the difference between InstaSpin Motion and InstaSpin FOC. Does FOC also use the patented ADRC implementation?

Hi Rushi,

The InstaSPIN-FOC is a sensorless motor control solution, which does not run the ADRC implementation. InstaSPIN-MOTION is a motion control solution. Thanks.

Hi Han,

What would you recommend for a PMSM motor application for an electric bike? - InstaSpin FOC or InstaSpin Motion?

Hi Rushi,

Depending on your application, if you would like to run the e-bike with torque control, InstaSPIN-FOC will be the solution. If you also need speed control, then you could use InstaSPIN-FOC together with InstaSPIN-MOTION. Thanks.
