摘要:實際的工業(yè)過程控制中，對于特定裝置的水位，溫度，壓力和其他一些變量常常需要保持一定的值，或者按照一定的規(guī)律變化，以滿足生產要求?？刂破魇歉鶕?jù)控制原理來對整個系統(tǒng)進行偏差調節(jié)，從而使被控對象的實際值與要求的期望值保持一致。PID控制器是一個在工業(yè)控制應用中常見的一種反饋回路部件。在其他控制規(guī)律使得系統(tǒng)存在穩(wěn)態(tài)誤差的情況下，PID反饋回路可以運用整定方法通過對參數(shù)的整定使系統(tǒng)保持穩(wěn)定，并使各項性能指標改善。 控制器的參數(shù)整定是控制系統(tǒng)設計的核心內容。本設計主要通過水箱模型，要求對常用控制器（例如PID）參數(shù)的整定方法進行研究，利用Matlab工具對控制器參數(shù)進行調整并對控制系統(tǒng)的性能影響情況進行仿真比較。 關鍵詞 水箱模型；PID控制器；MATLAB仿真；參數(shù)整定
Abstract:In the progress of production, in order to meet the requirement of production, the temperature, pressure, flow level and other process variables often require to maintain a certain value, or to change according to certain rules. The controller is based on the control principle of the whole control system deviation of regulation, so that the actual value of the controlled variable can be in agreement with the predetermined value process requirements. And the PID controller is a common feedback loop member in the industrial control applications. In the case of other control method causes the system to steady-state error, a PID feedback loop can make use of the tuning method by deserting the parameter setting system to maintain stability and the improvement of the performance indicators.Controller parameter tuning is the core content of the control system design. This design mainly through the tank model requires common controller (such as PID) parameter tuning method, the controller parameters using Matlab tools impact on the performance of the control system simulation comparison.
