【摘要】 本文论证了CAN总线技术应用于汽轮机调节系统中的可行性,把嵌入式操作系统与DSP嵌入式微处理器技术应用到系统的主控制器,并对实验室原理样机的硬件和软件体系进行了详细的分析和设计。全系统采用模块化结构,采用主控制器、上位机和CAN总线冗余技术使系统更加稳定可靠,单片机节点对调节系统的转速、功率等进行模拟操作和控制。本系统的主控制器的据处理采用了TI公司最新推出的32位定点DSP TMS320F2812作为主控制芯片,指令速度更快、兼容性能更好。另外由于TI公司为TMS320F2812提供的电源电路可靠性和稳定性不佳,本文对其电源电路重新进行了设计,经实验证明可靠性和稳定性都有了大幅度的提高。汽轮机调节的PID控制器采用了模糊自适应PID算法,并利用PSO算法寻找最优控制规则,仿真结果表明达到了很好的控制效果。更多还原

【Abstract】 This thesis proof feasibility applied in the steam turbine regulate system based on embedded operating system and CAN Bus Technologies. The system the master control applys embedded operating system and DSP embedded the processor technology.Analysised detailly and designed to the laboratory principle prototype about the hardware and software system.The entire system adapts the modular structure, used the host controller, on the position machine and the CAN bus redundant technology, which makes system stable and reliable. The monolithic integrated circuit node carries on the simulation operation and the control for the governing system rotational speed, the power and so on.This system used TI Corporation the newest promoted 32 fixed point TMS320F2812 as the master controlling chip. The speed is quicker, and compatible performance is better. Moreover, because the power circuit reliability and stable is not good, which TMS320F2812 provided by TI Corporation, So this these has carried on the design to its power circuit, after the experiment, the reliability and the stability had proved a large enhancement.PID controller that the steam turbine regulates carried on the fuzzy auto-adapted PID algorithm, used the optimum control rule with the PSO algorithm, the simulation result indicated it has achieved the very good control effect.更多还原
