This paper presents the speed control scheme of indirect vector controlled induction motor (EVI) drive. Voltage source inverter type space vector pulse width modulation (SVPWM) is used for PWM controlling scheme. An intelligent based on Fuzzy PI controller is developed for controlling the torque component Iq current of an EVI. The complete vector control scheme of the IM drive incorporating the FLC...
In this paper the dynamic performances of two speed control systems of DC motor are compared. There are compared dynamic features of the classical speed control system containing PI speed controller and the speed control system with time - minimal speed controller. Comparison is done on the basis of simulation investigation results.
The paper deals with the problem of robust speed control of electrical servodrives. A robust controller is developed using a nonlinear IP controller. The controller nonlinear characteristic is obtained due to fuzzy logic technique application. An original method of controller settings adjustment is presented. The use of this adjustment procedure ensures robust speed control against the variations...
In this paper a maximum power point tracking (MPPT) control system for wind-generator (WG) power applications is presented. The power electronics part consists of a boost DC/DC converter, a DC/AC three phase inverter and two control units: one controlling the boost converter ensuring the MPPT process and one controlling the inverter enabling the grid-connection and power flows control. The presented...
