Abstract
Controller constants play an important role in electric drive system dynamics. The vector control permits to consider the induction motor as all equivalent separately excited DC machine, as a result, the dynamics of the two machines are compared. Experimental realization and computer simulation are constructed under PI and PID controllers.
A sensitivity study for the controllers constants and for the machines time constant is carried our and demonstrated for both machines under the same conditions. The computer simulation of the electric drive systems is constructed using the MATLABSIMULINK software package.
