Abstract

The aim of this paper is to propose a simple feedback control strategy for multiple-input single-output (MISO) linear plants. One obtains the control transfer function of a class of each control input in a parallel control architecture. That is, every controller is driven by the same output regulation error. The parallel control scheme aimed to improve the disturbance rejection capabilities of the controlled process. A secondary variable is used in the above scheme mentioned to effectively reject disturbance to the biological system. In this way, the use of the recycle dilution rate as a secondary control input is in order to distribute the control effort. Simulation results are used to illustrate the control design methodology and the performance of the resulting controllers.
