Temperature control of a building using backstepping technique

Effective control strategy for building temperature regulation plays an important role in meeting peoples’ comfort demand. In this paper, the problem of temperature control is studied for two neighbouring rooms of a building using backstepping technique. The mathematical model of the considered building has strong coupled variables, which makes room temperature control more challenging. Firstly, in order to be convenient for controller design, the model is represented in state space form. Then, an appropriate controller is constructed using backstepping technique. Design parameters are introduced in controller design procedure. By choosing suitable design parameters, indoor temperature of the considered rooms can be regulated to desired value. Finally, simulation analysis and comparison are given including both cases in summer and winter, and simulation results show the effectiveness of the proposed controller.
