Besides dealing with the general calculations concerned with single and polyphase motors, one chapter is devoted to the special design of a three-phase motor of 200 h.p.; and two chapters, the first and the last, deal with the theory of the alternating current transformer. In appendix ii. ...

Due to the high degrees of Kalman filter, this technique requires complicated mathematical calculations that limits its application. The idea of Kalman Algorithm is based on determining 5 state variables for motor equations and using filter to view these variables. This method is sensitive to the ...
It contains the data and calculations necessary to re-generate the sine wave reference look-up table. This look- up table includes 3rd harmonics and is therefore not suitable as it is for bi-phase motor control. PWM frequency set-up on page 39. HyperTerminal file ...
8.5 Level 2 - Incremental Build Assuming section BUILD 1 is completed successfully, this section verifies the analog-to-digital conversion, Clarke and Park transformations and phase voltage calculations. Now the motor can be connected to the HVDMC board since the PWM signals are successfully proven...
This gives an output resolution of approximately 10 bits (± 500) but, using 24-bit calculations. On the other hand, by keeping the output resolution between 8 and 9 bits, the calculations required for PWM update can be sped up. Figure 34 shows that by decreasing the TIM1 speed to 12 ...
