为了提高电阻炉温度控制系统的动态性能和控制精度,对传统的PID算法存在的不足进行了分析,提出了基于AT89S51单片机的电阻炉温度模糊控制系统的设计方法,包括系统的硬件设计、软件设计和模糊控制器设计的方法;计算机仿真和工业现场调试结果表明,模糊控制器比PID控制器具有更高的稳态精度和更快的动态响应速度。在系统设计中,所采取的软、硬件设计措施及模糊控制器的设计方法具有一定通用性,也可以应用到其他设备的温度控制系统中。

In order to improve dynamic performance and control precision of resistance furnace temperature control system,this paper analyzes the lack of traditional PID algorithm,and brings forward temperature fuzzy control system design methods of resistance furnace based on AT89S51 single-chip, including hardware design, software design and fuzzy controller design. Through computer simulation and industrial field debugging,the results show that fuzzy controller than the PID controller has higher steady-state accuracy and faster speed of the dynamic response. In system design, the software and hardware design measures and fuzzy controller design method is universal, it can be applied to other equipment temperature control system.
