Switching Control of Parallel-Flow Heat Exchange Processes

摘要

In this paper, we treat switching control of parallel-flow heat exchange processes with distributed inputs. As the distributed inputs to the system, the output feedback control with a fixed gain is first applied. Then, it is shown that the Co-semigroup describing the closed-loop system satisfies the spectrum determined growth condition. Nextly, based on an energy function, we propose a switching law of the feedback gain. It is shown through a numerical simulation that, by switching unstable closed-loop systems, the whole control system can become stable.
