For the past several decades, the development of modern power electronics devices and motor control technologies makes Variable Speed Drive (VSD) popular in various application areas, such as on-road vehicles, home appliances as well as renewable energy field. Permanent Magnet Synchronous Machines (PMSM), one of the most promising motor technologies for its high power density, wide speed operation range and fast torque-speed response, has attracted great interest among various VSD applications. In this work, a PMSM based Integrated Start Generator (ISG) system is developed for a 50cc gasoline scooter to achieve higher efficiency and better road performance while still reasonably priced. The classical control theory based on root locus analysis and frequency response analysis is used to study a linear Single Input and Single Output (SISO) system. However, the PM machine as well as its drive inverter is a highly nonlinear, tightly coupled, multi-variable dependent system, which the classical control theory cannot be applied to directly. This work focuses on the analysis and compensation of these nonideal terms with an emphasis mainly on two perspectives: 1) Current control loop modeling with transfer function and the effect of various coupling terms and their compensations; 2) Inverter dead time investigation, its effect on the voltage output and new dead-time compensation method. The application of PM machine on an ISG scooter has a number of requirements and specifications of both the PM machine design and control algorithm implementation. One is the contradiction between mounting space limitation and high starting torque requirement. Another is the control challenge of speeding the motor to more than 10K rpm with only low resolution hall position sensors. A cost effective 1.5 KW Interior Permanent Magnet (IPM) machine and its drive inverter are designed based on these requirements. This IPM machine, its matching inverter and a 2 Ah 48V lithium-ion battery are well packaged on a prototype 50cc four stroke ISG scooter. Experiments are carrier out to test multi-modes of this ISG system including starting, acceleration, and regeneration.
