The main results of the paper are the systemic performance assessment and diagnosis methods for single pid and cascade pid control system , in which the set point tracking and regulation performance are evaluated using minimum variance as a benchmark 本文重点是针对pid控制器的特征,对单回路pid控制系统和串级pid控制系统给出了系统的性能评价方法和诊断方法。利用最小方差准则得到二者的设定点跟踪性能和调节性能。
Pid control technique is reliable , stable and its structure is simple . it has the advantage to eliminate the error , but its efficiency depends on its factors . because of the conflict between quickness and over setting point , it probably can not satisfy the control demand Pid控制结构简单、可靠性强、容易实现,并且可以消除稳态误差的优点,但其性能取决于参数的整定情况,其快速性和超调性之间的矛盾关系使它不一定满足被控对象的技术要求。
The system of traffic flow predictive control with pseudo set point , predictive model , moving optimization and feedback adjustment could realize performance assurance control of traffic flow system , which provides global analysis and decision making support for the prevention and recovery of traffic congestion 基于伪给定、预测模型、滚动优化和反馈调节的交通流预测控制系统能够实现有性能保障的交通流系统控制,为交通拥堵预防和拥堵恢复畅通提供全局性的分析和决策支持。
Control of discharge - sand gate discharge - sand gate adopts electro - hydraulic handspike ; it uses displacement transducer to measure opening of sluice gate ; when opening of displacement transducer is smaller than set point , the electro - hydraulic handspike will open this gate ; when opening of displacement transducer is larger than set point , the electro - hydraulic handspike will close the gate 卸砂门采用电液推杆,由位移传感器检测砂门的开度,当位移传感器检测的开度小于控制系统的给定值时,电液推杆工作将门开大,当位移传感器检测的开度大于控制系统的给定值时,电液推杆工作将门关小。
( 4 ) the man machine interface has been devised , which can show the working status and digitally display multichannel electrical parameters . < wp = 4 > via keyboard , users can input the set point of two kinds of auto - control system and manually operate control systems , whose manual / auto switch is unperturbed ( 4 )设计了电源的人机对话接口,为用户提供了工作状态指示和四类电参数的数字显示,支持两类控制系统给定值键盘输入、手/自动无扰切换和键盘手动操作等功能。
