摘要:AbstractIndoor climate control is a central topic in modern buildings. Especially office spaces have to provide a high comfort for the occupants while at the same time the building operation should require as little energy as possible. Moreover, an upcoming topic in building automation is a fast reaction to user feedback. The traditional design of a room temperature controller focuses solely on a good rejection of input disturbances such as variations of occupancy and solar radiation. Since the transfer functions of the user feedback and the input disturbances to the room temperature differ, a fast reaction to user feedback requires rethinking the design of a room temperature controller. Altogether, there is a desire to use modern controllers for room temperature control.To ensure indoor comfort, the room temperature has to be kept within a certain interval. In this paper, the internal model control method is extended such that the controlled variable is kept in the tube defined by this temperature interval. The main idea is to compute an admissible tube for the planned trajectory. This results in an interval for the control input, which provides a degree of freedom. This is used to minimize the energy consumption. For the implementation in reality, the proposed controller is discretized in time. To ensure a good disturbance attenuation, the controller is combined with a Kalman Filter.The closed-loop behavior of the developed controller is validated in a real building and compared with a state-of-the-art controller.
