[Industry research] statorflux DL : 0: In this paper an approach to estimate the speed and the stator flux linkage of a three Phase induction motor by means of an algorithm using dSPACE is proposed. Emphasis is given on reduction of the problem of saturation associated with the pure integrator, while flux estimation. Speed is estimated using a sensor (MOC7811) mounted at the motor shaft. Experimental investigation is carried out on a 1 H.P. motor, a digital inverter controller, an IGBT power module for inverter/chopper and dSPACE Controller Board (CP1104). Real time signals like three phase currents, PWM Pulses, fixed DC link voltage and response of sensor MOC7811 are the input parameters to the Dspace controller board, and using these parameters stator flux and speed is estimated.

[Industry research] Control-of-Three-Phase-PWM-Rectifiers DL : 0: As I have marked in the attached image, there is a PI controller, which is not necessarily a PI controller and could have several poles or zeroes. I have simulated this system nearly successfully and the only thing I am struggling with is the controller parameters. I tried lots of controllers with different coefficients, but it still does not operate properly. I have attached the output DC voltage signal, the output voltage should be 500v DC, while it is fluctuated with an undesired start-up and this is directly dependent on the controller coefficients.
