摘要:
A programmable dynamometer is proposed where the user can define the steady-state and inertial torque-speed characteristic of the load. Rotating machinery can be tested on this dynamometer to determine their transient and steady-state characteristics with a practical load. The user inputs the desired load characteristics by selecting polynomial and inertia coefficients. The system uses proportional-integral (PI) controllers to control a three-phase induction motor using indirect field orientation. Simulations show that the dynamometer offers excellent tracking of the desired torque-speed characteristic and simplicity of use
