Real-time air conditioner zone temperature control by cascaded intelligent PI

In this paper, we control an air conditioner system thought the application of a newly developed Intelligent Proportional Integral (i-PI) Controller that regulate a zone temperature to desired setpoint temperature. This method approximates the unknown nonlinear system function and is applied to the problem of controlling compressor for a vapor compression cycle system where evaporating pressure target is automatically determined by the i-PI so that zone temperature is met to desired setpoint.
