The use of variable geometry turbocharger (VGT) is an effective method to improve the low working condition of supercharged diesel engine. Here, a method of controlling the stepper motor with STC89C52 single chip microcomputer as the core, using photoelectric isolation for input and integrated driver chip for output is introduced to realize the control of VGT. The experiment shows that the design scheme is feasible and has certain practical value.
