用于温度控制系统的计算机数字仿真

把计算机数字仿真技术运用于生产过程的PID控制系统中,实现对控制系统的最优化控制,是信息技术应用于控制系统的一个范例。本文提出一种适用于一般PID控制系统的数字仿真系统的建立方法,并对其数学根据进行了阐述。通过一个在实际PID温度控制系统中应用数字仿真的实例,给出了实际PID控制系统中建立数学模型和实现最优控制的一般方法和技术。并给出了以MCS-51微控制器为核心建立实际PID温度控制系统的技术和方法,此系统的实际控制效果表明:PID控制数字仿真系统对于实际控制系统的控制具有很好的指导意义。

Computer simulation of temperature control system

The computer simulation technology, which applied to optimize control of PID control system, is a good example that control system was reformed with information technology. This paper presents the universal method and technology of mathematical modeling using C language in PID control systems, and mathematical theory of computer simulating. This paper introduces the method and technology of the design of practical temperature PID control system that is based on microprocessor. The controlling results of practical temperature PID control system verified that the computer simulation can be used to guide the design of practical PID control system.
