Permanent magnet synchronous motors (PMSM) are widely used in low to mid-power applications and high-performance drives. They are preferred over brush-type motors and gradually replacing induction motors in various fields of application due to its advantages. Many researchers are proposing new control methods of PMSM drive system. However, the PMSM system is nonlinear and consists of time-varying parameters with high-order complex dynamics. Due to these factors, researchers cannot rely only on simulation results to prove superiority of their proposed controllers. To validate the results obtained by simulation, experimental validation is necessary, where a closed-loop PMSM drive system prototype has to be developed. This paper describes the development of a PMSM drive system prototype with closed-loop current, speed and position feedback using dSpace DS1104 controller board for a 1.93kW three-phase interior-mounted permanent magnet synchronous motor used for experimental validation of a proposed modified fractional order sliding mode speed controller. Using this prototype, the performance of any newly proposed control methods in real applications can be verified. Appropriate signal acquisition procedures of the feedback signals, as described in this work, are crucial to ensure the accuracy of closed-loop performance of the developed drive system.
