Simulation of marine electric auxiliary turbocharger drive control system

In this paper, for the application requirements of an electrically-assisted turbocharger brushless DC motor (BLDC), the drive control is simulated and studied in the Simulink platform. By establishing the motor control model, the speed and current response characteristics of the inductors square wave closed-loop control under different operating conditions are analyzed in detail, and the dynamic response performance of the system is significantly improved by optimizing the PID control parameters. The variable operating condition characteristics and stability of the electrically assisted turbocharger are analyzed, which provides the theoretical basis and data support for optimizing the control strategy and improving the system’s reliability.
