摘要: Abstract A multivariable control strategy is developed to the polymer molecular weight in emulsion polymerization processes while maximizing reaction rate by manipulating jacket temperature and monomer flowrate. In order take into account process nonlinearity, input–output linearizing considered. cascade of two nonlinear observers estimate heat number moles radicals particles. By introducing these estimations available measurements model, could be estimated online. The online estimation was validated experimentally seeded styrene for which model well known. It also methyl methacrylate where a simplified identified.
