Design of PID controller with adaptive feedforward gain in residential air conditioning system to improve performance
The current environmental issues and the rising human need for solutions with best comfort levels and lower cost has resulted in the realization for the energy consumption in the environment. Therefore, in the process of improving efficiency and performance of the residential air conditioning system control techniques generally used in the HVAC systems. The research focuses on the design of PID controller with adaptive feedforward gain for residential air conditioning system. The adaptive controller parameters are adapted depending on the estimates of the system thermal load. The project proposes an approach to design a controller, which is capable of maintaining comfort levels under time varying thermal loads. A mathematical model of the system was generated after studying the dynamics of the system. The residential air conditioning system composed of a compressor, heat exchanger, condenser, evaporator and thermostatic expansion valve. The pressure of the AC system is measured by transducers, and the temperature by sensor. A detailed simulation environment was created using the Matlab/Simulink. The main goal was to derive a mathematical model of the HVAC plant and to design a PID controller with adaptive feedforward gain, which is capable of controlling the disturbances within small amount of time and zero error.
