The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

This video shows the working mechanism of Physik Instrumente (PI)’s Hybrid Stage. PI offers a unique hybrid concept with parent position measurement and closed-loop control. Some of the key features ...

We are now on the eight part of a ten part series about teaching your PI controller to behave like you want it to. At the heart of this discussion is a proposed tuning technique which allows you to be ...

Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...

At last! Let’s take what we have learned so far and see how it applies to Field Oriented Control (FOC) systems. Figure 1 shows a typical field oriented system incorporating TI’s new FAST sensorless ...
