自动调节型阀门微机控制器是一种带有PID自动调节功能、且参数在线可调并与执行器融为一体的机电一体化产品。该产品具有通用性好和实用性强的特点。本文主要叙述为了使控制器实现上述特性所采用的一些自动调节方法(主要有PID参数的模拟式整定、增量计算位置输出以及控制器如何与执行器融为一体等),其内容主要包括调节系统的分析与设计、算法推导以及8039单片机为核心的硬件和软件设计等。 Automatic regulating valve microcomputer controller is a PID with automatic adjustment function, and the parameters can be adjusted online and the integration of the actuator mechatronics products. The product has good versatility and practicality characteristics. This article describes some of the automatic adjustment methods used in order to achieve the above characteristics of the controller (mainly PID parameters of the analog tuning, incremental calculation of position output and how the controller integrates with the actuator, etc.), its contents include adjusting System analysis and design, algorithm derivation and 8039 single-chip microcomputer as the core hardware and software design.
