Experimental Verification of Closed Loop Speed Control of PMSM using DSP 2407

Use of electrical motor is inexorable in contemporary and control of the electrical motor is essential in all most all practical applications. There is a tremendous increase in demand for permanent magnet drives which have convenient characteristics like lesser energy costs, optimal performance, reduced acoustic noise and more. The traditional machines like single-phase AC induction, including split phase, capacitor-start, etc. cannot provide the above features. Among these PMSM applications used in every part of the market such as consumer appliances, industrial control, and automation, aviation, etc. These PM drives are helpful as variable speed drives with reasonable accuracy. The problems encountered with these motors for variable speed operation eliminates with the advancements in technology in the fields of power semiconductors, microprocessors, adjustable speed drive control schemes. These improvements have been combined to enable reliable, cost-effective solution for a broad range of flexible speed applications. This paper deals with speed control of PMSM in the closed loop which is simulated & developed using DSP 2407. The mathematical model of PMSM, using modeling capabilities of Simulink is implemented. Other hands, a hardware implementation of such systems using DSP plays a vital role in speed control methodologies.
