The Design of the Speed Control System of Supercharger Using Microcontroller

Abstract

The cruise control system regulates the car's speed, focusing on simulating and assessing the air compressor's speed control within the engine speed control system. Comprising a microcontroller PIC30 main board, H-Bridge DC motor drive board, encoder, 12V DC motor, supercharger, and PC interface with MATLAB and Simulink, the system aims for efficient speed control. Simulation results showcase the impact on DC electric motor speed control, emphasizing clarity and stability. The study outlines distinct outcomes: 1) Deactivation of the control system. 2) Activation at 1100 rpm. 3) Operation at 1200 rpm. 4) Functioning at 1400 rpm. Observations reveal that without the air compressor, the system struggles to control rotational speed. Conversely, with the control system engaged, consistent average errors of 0.63% occur across the three specified speeds. The setting time remains under 2 seconds. Subsequently, the control system autonomously readjusts the speed to the predefined specifications. The research highlights the system's effectiveness in achieving stable speed control, offering insights into its practical application within automotive engineering.
