摘要
九点控制器是一种新型的智能控制器,对相当广泛的被控对象具有适应性,鲁棒性强,在稳定控制、延时滞后控制方面具有很好的控制效果。并具有控制算法简单、易于工程实现的优点;以PLC作为温度控制系统的核心,采用九点控制器的控制策略,设计了塑料挤出机的温度控制系统。实际应用表明,该系统调试简单、稳定可靠,能有效的减少超调、提高稳态精度。
The nine-point controller is a new type of intelligent controller which hasnt strict limit to object and has strong robustness and has good effect on control of stability and delayed time. A new temperature control system for plastics extrusion machine is studied and designed, in which PLC and nine-point controller are combined。Practice prove this system has following advantages: convenient debugging, high reliability, short adjust time, small overshoot and high accuracy.
