Dynamic Performances of Adjustable Speed AC Drives Part 2: Control and Simulation of AC Machines

摘要

In this part, an alternating current machines drives and control methods were implemented. Fortran Language program were used for digital simulation. A six-step inverter and sinusoidal pulse-width modulation inverter are used for the induction machine. With indirect vector control method introducing into the current-controlled dead-beat inverter derive system, the induction motor can be operated in all four quadrants and speed can be controlled from zero to full value where a smooth and fast torque response is obtained throughtout the range of the operation. Different types of simulation examples are examined for AC machines and results are discussed.
