This is a unique book and the first to focus on direct eigen control for AC motors. It presents a clear and concise explanation of the new sampled vectorial method that is designed to control all AC motor types: induction machine (IM), surface mounted permanent magnet synchronous motor (SM–PMSM) and interior permanent magnet synchronous motor (IPM–SM).

This totally new control method supersedes the two well–known direct control solutions Direct Self Control (DSC) and Direct Torque Control (DTC or MPDTC) and takes into account all technical constraints and technical limits without overshoot or lagging. It can also be used to control input filter current and voltage of an inverter feeding an AC motor. The sampling period and voltage vector sequences can be chosen independently of control performances, allowing inverter PWM frequency and motor current harmonic level optimization.

Explained with the Kalman s Observer, the text describes how to practically implement, in real time, this method of dead–beat machine control in all three types of AC motors. Helpful additions include:

  • Straight–forward mathematical descriptions and solutions
  • Full AC motor modeling by the discrete–time, state–space representation
  • PWM optimization method
  • Practical complex software implementation of the control
  • Various examples that show the control performances in traction or braking mode
  • Comprehensive simulations described in a way that is easy to understand and to reproduce on a computer, with simulation software files available on a companion website

Highly accessible, this is an essential reference for researchers in the field of drive control, postgraduate students studying electric machines, and electric engineers in the field of electric railways, electric cars, wind turbines, plane surface control, and military applications. Final year undergraduates and engineers in the field of machine tools, robots, and rolling mills, will also find it of value.
