Safety Enforcement In Process Control Systems - A Batch Evaporator Example

This contribution presents an approximation basedsafety enforcement scheme for a batch evaporatorbenchmark problem. Typically, safety enforcementin chemical engineering is a hybrid problem: theplant is (or parts of it are) represented by a continuousmodel, whereas the safety enforcing device isusually based on discrete intervention rules. Approximatingthe plant model by an automaton convertsthis problem into a purely discrete one, provided twoconditions hold: the approximation...
