Abstract

A three-phase induction motor direct torque control laboratory set-up for simulation and experimental activities is presented in this paper. It includes sliding-mode controllers and uses a sensorless method to estimate rotor speed. The objective of this setup is to present to the students a simulation tool based on Matlab SimPowerSystems toolbox with the possibility to check simulation results against a DSP based experimental system. The set-up provides to the electrical engineering students an excellent learning tool for nonlinear control studies using as example the variable speed three-phase induction motor control. Linear control systems are extensively studied in electrical and computer engineering theoretical and experimental sessions while non-linear control systems aren’t.

Marcos Vinicius Lazarini, Electrical and Computer Engineering School University of Campinas (UNICAMP) – Brazil

was born in São José dos Campos, Brazil on May 29, 1978. He received his Bsc degree in Computer Engineering with emphasis in hardware development from University of Campinas, Brazil, in 2004, and now is pursuing his M. Sc degree in Electrical Engineering from Unicamp. His research interests are in programming for embedded devices in general, digital signal processing theory and control theory applied to motor drives.

Ernesto Ruppert Filho, Electrical and Computer Engineering School University of Campinas (UNICAMP) – Brazil

was born in Jundiaí, Brazil in 1948. He received his Ph. D degree on Electrical Engineering in 1983 from University of Campinas (UNICAMP), Brazil and also his M. Sc Degree in 1974 and his B. Sc in 1971 in Electrical Engineering from the same University. He is with UNICAMP as a Faculty since 1972 working in the areas of electrical energy systems, electrical machines and power electronics. He had been working for General Electric and also for Villares Electrical Equipments in Brazil designing motors and generators for about 15 years. His fields of interest now are superconductor current limiters, control of electrical machines and power electronics, areas where he published several papers.
