Position Sensorless Control of PMSM with Innovative Regenerative Braking for e-Rickshaw

Abstract

Permanent-magnet synchronous motor is being preferred in transportation due to its innate features. This paper presents the simulation and PIL (Processor-in-Loop) verification of speed & position sensorless control of Permanent-magnet synchronous motor for e-Rickshaw application. The various components and control algorithm fore-Rickshaw are modelled in PSIM-a power electronic converter simulation software and embedded graphical programming environment. Interface modules and algorithm are modelled using TMS320F28335 DSP embedded peripherals and integrated with inverter & motor for drive system simulation. An innovative regenerative braking scheme is proposed for e-Rickshaw to achieve efficient energy recovery. Braking scheme logic is derived from zero crossing of back EMF voltage. The simulation results are verified by PIL experimental results. Experimental results reveal efficient energy recovery by which e-Rickshaw running per charging can be enhanced.
