Abstract: A projector control system and a control method corresponding to same. The system includes a main controller, a dynamic current adjusting module, a color wheel controller, a color wheel rotation speed feedback module, and a light source; the dynamic current adjusting module includes a DLP module, a light source controller, and a power supply module; the color wheel rotation speed feedback module generates a feedback signal; the DLP module receives the feedback signal, and the DLP module receives dynamic brightness information and sends processed dynamic brightness information and a control signal to the light source controller according to the feedback signal; the light source controller controls the power module according to the received processed dynamic brightness information and the control signal sent by the DLP module to turn on a power switch and output a corresponding current value.
