Design of Embedded Control System Based on ARM9 Microcontroller

This paper mainly focuses on the design and realization of embedded control system based on ARM kernel. Firstly, hardware structure, configuration and signal detection, processing of the control system based on ARM are described. Secondly, the system application programs, including main control program, user operation interface program, keyboard program and development of drivers for some S3C2410X related functional modules are described. Lastly the closed-loop control of parameter is achieved by way of PID and NN. As practical experience shows, after introducing the control system into the parameter control for microbiology fermentative process, the design of the system reaches expected effect, realizes relevant functions and shows a broad market prospect.
