| Abstract |
AC motor drives employing Direct Torque Control (DTC) have been shown to
provide excellent dynamic torque response and robustness to parameter variation. In many
cases an outer speed loop is also included to improve the dynamic speed response, often
consisting of a simple Proportional-Integral (PI) controller. In this paper a practical
implementation of DTC is presented which uses a fuzzy logic speed controller in the outer
loop. Fuzzy logic controllers of this type are highly robust to parameter variation and can
provide faster dynamic response than conventional PI controllers and so can make better use of
the fast torque response possible with DTC. The controller is implemented in a TMS320C31
Digital Signal Processor (DSP) and is used to control a 7.5kW induction motor. |
