基于区间二型模糊PD控制规律的中央空调性能试验台控制

空调性能试验台系统主要用于测试空调的制冷性能,是一个耦合性强、滞后时间大、高不确定性的非线性系统。为解决采用PID等传统控制方法控制效果不佳的问题,分析了空调试验台系统的控制原理,建立了试验台系统的数学模型,研究了区间二型模糊PD控制规律,并将其应用于试验台系统。仿真结果表明,区间二型模糊PD控制规律具有较好的控制效果,在强耦合、大滞后的复杂系统中具有广阔的应用前景。

Control of Central Air-Conditioning Performance Test System Based on the Interval Type Two Fuzzy PD Control Rules

Central air-conditioning performance test system is used to test refrigeration performance. Because the system is a strong coupling, long delay time, high uncertain and nonlinear system, using PID and other traditional control methods have poor control effects. The control principle of central air-conditioning performance test system is analyzed in this paper. The mathematical model of test system is established. The interval type two fuzzy PD control rules is proposed and used to the test system. Simulation results expatiate the proposed rules have better control effects and broad application prospects in coupling system with large delay.
