DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...
The most common arrangement, which is used with only minor variations from small drives of say 0.5 kW up to the largest industrial drives of several megawatts, is the so-called two-loop control. This ...
Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...
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 ...
Proportional integral derivative (PID) control is the most common type of feedback control algorithm used in industry today. Because the PID algorithm can be tuned, it has been successfully used to ...
TOKYO--(BUSINESS WIRE)--Azbil Corporation (TOKYO:6845) has started sales of the model C1A single loop controller, which features high accuracy and fast response and reduces the burden on personnel, ...
