A general linear method is described for controller design for a speed-controlled current-source induction motor (CSIM) operating under two different control strategies: slip frequency control (SFC) and torque angle control (TAC). The designed controller ensures asymptotic stability and satisfactory dynamic response of the electric drive system. Digital(More)
A new electrical transmission drive that insures an adjustable constant speed difference between a pair of mechanical shafts independent of load conditions or speed level is described in the paper. This generalized electrical shaft comprises two rotor interconnected induction machines, fed from different frequencies and two dc machines forming a double(More)
