Abstract :
The control of copolymer composition is an important industrial problem, which has direct implications in quality attributes of the product, production rate, and the way the process and its equipment are designed and operated. With nonlinear control tools and with outputs having relative degree one (which is an important robustness-oriented specification) it is established that the election of the composition of the unreacted most reactive monomer and the average composition of the converted least reactive monomer leads to the fastest copolymer composition response
