Practical Control of Electric Machines for EV/HEVs
Design, Analysis, and Implementation
Chapter
This section elaborates the pulse width modulation (PWM) control methods of voltage source inverters (VSIs). The Sinusoidal PWM (SPWM), Third harmoic injection PWM (THIPWM) and space vector PWM (SVPWM) are dis...

Chapter
In this chapter, an equivalent circuit model is derived for analysis of the torque-slip characteristics and efficiency of induction machines. This model is not intended for transient dynamic analysis. A more r...
Chapter
This chapter presents the root locus of the induction machine model with the associated dam** ratio when the parameters of frequency \(f_s\) ...
Chapter
This chapter presents the well-known vector control approach to control the ACIM torque accurately and dynamically. Various control strategies as well as their performances are analyzed and discussed in this c...
Chapter
This chapter presents the direct rotor field oriented control. The core of the flux oriented control is the estimation of the relevant ACIM parameters, including the rotor flux, rotor resistance and rotor indu...
Chapter
Driven by the environmental concerns, it is now commonly acknowledged that conventional fossil fuel-powered vehicles will gradually phase out and be vastly replaced by electrified vehicles. In order to boost t...
Chapter
In this chapter a reference frame that rotates at the same speed of the rotor flux is applied to setup a model for induction machines. The system behaviour at the rotating frame is more like DC motors, but the...
Chapter
This chapter is to illustrate the method that uses the constant Volts Herts (V/F) and the slip speed to control the ACIM torque. It is known as the scalar torque control. This technique can achieve satisfactor...
