Abstract

The invention discloses a design method for a PAC controller based on intelligent control algorithms. On the basis of a conventional PAC controller, the invention can improve the control accuracy and control response, and meet higher control requirements by using intelligent control algorithms such as an improved PID control algorithm, a variable universe fuzzy PID control algorithm, a PID control algorithm based on a neural network. In an aspect of network communication, the Ethernet, CAN bus and other means of communication are added on the basis of conventional serial ports 232 and 485, and Modbus-RTU, Modbus-TCP, CANopen, custom protocols and so forth are used for achieving network interconnection. An integral windup prevention algorithm, an algorithm for differentiation of control variables, a differential forward algorithm and the like are added on the basis of a conventional PID, the PID effect can be significantly improved, the response speed is increased, and the control overshoot is reduced.

Description

technical field [0001] The invention belongs to the field of industrial automatic control, and relates to the design of an embedded PAC controller, high-precision temperature control, intelligent control algorithm and the like. Background technique [0002] In the production process of industrial manufacturing, the demand for control is getting higher and higher. PAC controllers have some notable advantages in control performance, information processing and network communication capabilities. PAC controller combines the inherent reliability, robustness and distribution characteristics of PLC. Compared with PC control, PAC uses a real-time operating system, which has incomparable advantages in processing performance such as real-time and deterministic PC. However, the traditional PAC controller is relatively simple in the control algorithm. When it comes to some complex algorithms, the method often used is combined control with a PC, which also exposes some defects, such as ...
