Abstract
In this paper, we propose a new method for control of large-scale multi-rate
systems with linear dynamics that are coupled via inputs. These systems are
multi-rate systems in the sense that either output measurements or input
updates are not available at certain sampling times. Such systems can arise,
e.g., when the number of sensors is less than the number of variables to be
controlled, or when measurements of outputs cannot be completed simultaneously
because of applicational limitations. The multi-rate nature gives rise to lack
of information, which will cause uncertainty in the system's performance. A
distributed model predictive control (MPC) approach based on Nash game theory
is proposed to control multi-agent multi-rate systems in which multiple control
agents each determine actions for their own parts of the system. Via
communication, the agents can in a cooperative way take one another's actions
into account. To compensate for the information loss due to the multi-rate
nature of the systems under study, a distributed Kalman Filter is proposed to
provide the optimal estimation of the missing information. Using simulation
studies on a distillation column the added value of the proposed distributed
MPC and Kalman Filter method is illustrated in comparison with a centralized
MPC with centralized Kalman Filter, and a distributed MPC method with a fully
decentralized (i.e., no communication) Kalman Filter.
