The Research Of The Superheated Steam Temperature Control System Based On ARM

At present, with the development of technology, embedded system are widely applied in the industry control field. It is a special computer system with the high-performance and lower power consumption character, integrating hardware, real-time operating system and applying software, and it has become to one of the important direction in the control area.The superheated steam temperature control system has the characteristic of time-varying, nonlinearity, large delay and the PID parameter need be modulated under different conditions. Aiming at solving these question, the whole design ideology and hardware realization of the superheated steam temperature controller based on ARM, are presented in this paper.Firstly, the paper studied the control strategy and object controlled in the superheated steam temperature control system, integrating fuzzy control, then the self-tuning cascade fuzzy PID controller algorithm was proposed and simulated in the Matlab SIMULINK environment. The results are demonstrated that the parameter has well Self-tuning capable, and its anti-interference and overshoot ability can completely meet the demand of the superheated steam temperature control system.The hardware circuit was designed based on the SAMSUNG ARM9 S3C2410 processor. A minimum system was set up, and then enlarged the peripheral circuit for actual need, including the man-machine interaction module. The signal acquainted and processed entry to the 10-bit ADC module of S3C2410 and output the control signal with D/A module. The transplantation of the real-time operating systemμC/OS-Ⅱand software design process are introduced at the end.The design of super superheated steam temperature control system based on ARM in this paper has better anti-interference capacity of adaptation, as well as the good control quality and robustness which can meet the system control needs. Meanwhile, the friendly human-machine interface is the characteristic of this design, which realized the monitoring of the controlled object. Figure [52] table [4] reference [52]...
