The four-wheel torque and the four-wheel corner are controlled independently in the four-wheel independent drive and steering electric vehicle with steer-by-wire system. The road feeling simulation is different from the traditional two-wheel steering vehicle. The paper is suitable for the four-wheel steering vehicle simulation control algorithm. The principle of road feeling simulation control is...
With rapid electrification of transportation, it is becoming increasingly important to have a comprehensive understanding of criteria used in motor selection. This paper presents the design and comparative evaluation for an interior permanent magnet synchronous motor (IPMSM) with distributed winding and concentrated winding, induction motor (IM), and switched reluctance motor (SRM) for an electric...
Interior permanent magnet motors (IPM) have been widely used in electric or hybrid electric vehicles due to their high efficiency and high power density. Frequent starts and stops, acceleration and deceleration of vehicles present heavy requirements for the drive motor. In this paper, a 4kW interior permanent magnet motor is designed for a small range-extended electric vehicle. A case study has been...
This paper investigates the electromagnetic and vibrational characteristic of an interior permanent magnet machine (IPM) over the entire torque-speed range based on the model of 2004 Toyota Prius IPM motor. First, the dominant electromagnetic radial force directly causing vibration is calculated based on optimal operating plane, which covered by maximum torque per ampere (MTPA), current limit curve,...
Variable speed wind turbine control is essential in extracting maximum electric power out of available wind power. The paper presents a memory-based method for variable speed control of wind energy conversion systems. The fundamental idea behind the method is to use certain memorized information (i.e., current rotor speed tracking error, most recent speed tracking error, and previous control experience)...
