Independent Position Control of Two Permanent Magnet Synchronous Motor Drives Fed by a Five-Leg Inverter

Abstract

-This paper presents the experimental test results of the independent vector control characteristics of two three-phase permanent magnet synchronous motors (PMSMs) fed by a five-leg inverter (FLI). Recently, the use of PMSM is more and more spreading in industrial field. It has the features of saving-weight and high-efficiency compared with DC motor and induction motor (IM). The maximum feature of the PMSMs is the realization of high performance position control. The independent position control validates for the factory automation (FA) apparatus as machine tool. If the independent position control of two motors with the FLI may be realized, the belt conveyer used at the FA apparatus as machine tool will become possible not only one dimension but also two dimensions with single inverter. In this paper, experimental results are verified for the independent position control of two PMSMs fed by the FLI with the vector control.

Optimized Inverter Circuits for Driving Dual AC Loads for Home Solar Water Pumping

“…In certain applications, there is a practical need to control two or more loads simultaneously [1] independently. However, the conventional approach of using individual converters for each load introduces complexities in designing, operating, and maintaining individual converters and their control circuits [2][3]. This paper addresses the challenges associated with controlling two independent loads with a single converter topology while leveraging the power of machine learning techniques.…”
