Energy efficiency in buildings using MPC and LQI with Kalman filtering

This article proposes a strategy for efficient heating in a building during winter season. The main objectives are to heat the building by combining non-renewable energy sources with renewable ones, to keep the indoor air temperature at a reference according to the hours of occupancy by using model predictive control and linear quadratic integral control with Kalman Filtering and to reduce the costs of non-renewable electric heating by taking into consideration the price of electricity which varies over 24h. The approach is simulated in MATLAB and the results are presented.
