Simulation of the dead-time compensation in vector-controlled induction motor;

But the magnitude of output voltage will be affected and it’s waveform will be distorted by the existence of dead-time in its main circuitry without dead-time compensation.

The dead time effects on the output voltage of the PWM voltage source inverter and a classification on dead-time compensations are presented.

The design method and implementation technology of the proposed digital controllers were recommended, which comprised the harmonic detecting method with high accuracy, control arithmetic of variable structure, dead time compensation and hardware implementation.

Finally, a dead time compensation method based on control chip MR16 was implemented.

The survey has been made on three sub areas,they are PWM basic technique,PWM technique combined with current control,and PWM dead time compensation technique.

Methods On the basis of conventional composite control with the deadzone compensation method, a comprehensive control approach with the deadzone and self adjusting feedforward compensation was proposed.

The deadzone compensation using adaptive fuzzy logic is studied To implement self tuning scaling gains of the input fuzzy variables ,a weight function is constructed through defining a state distance from the ideal equilibrium point When the system is close to the stable state, the scaling gains notably enlarge and the adaptive deadzone compensation is accomplished.
