Abstract
The control of nonlinear non-minimum phase processes by using traditional geometric approaches has lead to the development of specific design methods, such as the statically equivalent output approach. On the other hand, alternative design methods based on physical models, energy and mass balances, and the concept of passivity have been applied to a wide range of electrical and electromechanical systems. However, their application to process control has been limited. In this work, a comparative analysis of both design control approaches is presented. A standard continuous stirred tank reactor example is used to illustrate the differences among the approaches and the performances attained in both cases.
