Researches on Load Balancing Control Problem for the Systems with Multiple Parallel Entities Using Differences Control Technique

Load-balancing problem, which covers a large area in engineering fields where several parallel entities share the same load on the systems, is studied. A control technique for solving such problem, called differences control technique (DsCT), is investigated. Two types of systems whose parallel entities can be approximated respectively as an integral and a first-order-plus-dead-time (FOPDT) model are examined. The issue of system balanceability is elaborately addressed, and a sufficient condition for the systems to be balanceable is given. An application example is presented to demonstrate the effectiveness of the DsCT technique for solving the load-balancing problem.
