Autocontrol of Water Condenser Based on PID Controller
To maintain the outlet temperature at the desired set-point, a high-order outlet temperature control model is established for a water condenser, and different PID controller design methods are applied to its temperature control process. The control function model is based on the analysis of the heat balance equation and the heat transfer rate equation. The design process of three different PID control methods, including Ziegler-Nichols Method, Modified Ziegler–Nichols Formula and the Optimum PID Controller, together with the unit step response consequence are provided and compared, and the numerical simulation results show that the Optimum PID Controller has a favorable control performance.
