| Abstract |
This paper deals with induction motor deadbeat
control. The main objective of such a control is the flux and
torque dynamics, against feeding voltage drop and load
torque disturbances, to comply under voltage and current
limitations, the specific railway requirements, including line
and motor harmonic management. A novel discretization
method of the induction motor state-space equations is
carried out, which leads to their exact inversion, and
therefore to the calculation of the voltage space-vector
components, to obtain in one-step, the flux and torque
reference inputs. The magnetization current set-point is
analytically calculated as a function of flux reference in
transient analysis. This method is generalized to other types
of motors or actuators such as surface mounted permanent
magnet synchronous motors. |
