LINEARIZING CONTROL OF A CLASS OF NON-LINEAR CONTINUOUS PROCESSES

Abstract

Most of the continuous industrial processes working inside a large operating range can be modelled by non-linear state equations that are linear in control. A way for controlling those processes can be a closed loop linearization. It is shown that, when the solution exists, we get an explicit non-linear state feedback control law. The linearizability condition is demonstrated and it is shown that the control law may involve some singularities. Two practical applications on chemical and hydraulic pilot plants are presented.
