A simple bumpless transfer mechanism with application to multi-effect evaporators

In many applications one needs to switch between control laws. This requires some form of bumpless transfer. Here we propose a simple bumpless mechanism for possible implementation on a set of multi-effect evaporators in a sugar mill located in Queensland, Australia. The ultimate goal of this study is to allow on-the-fly testing of different controller designs and exchanging of control authority to achieve increased performance.
