AI Technical Summary
Existing constant temperature and humidity test chambers suffer from low humidity control accuracy, high energy consumption, and short compressor life under high temperature and high humidity conditions. Furthermore, the existing dual compressor switching control lacks the ability to predict future humidity change trends, resulting in lag response and poor energy efficiency.
A humidity control system employing dual compressor collaboration and model predictive control achieves high-precision humidity regulation and energy consumption reduction through a discrete-time state-space prediction model and a rolling time-domain optimizer. The system utilizes recursive least squares method to identify model parameters online and combines a mixed-integer quadratic programming solver to optimize control commands.
It achieves high-precision humidity control, significantly reduces energy consumption, extends compressor life, and has adaptive capabilities to meet optimal control requirements under different load and environmental conditions.
