The combination of linear and nonlinear controls results in a simple and effective controller for a class of nonlinear processes, as illustrated by the simulations in this paper.
Furthermore, the 2-port control structure allows the transparent design of effective controllers for processes with non-minimum phase characteristics, or inherently unstable open-loop dynamics.
An important challenge to overcome is the modeling of drillstring dynamics and the design of effective controllers to reduce undesirable behavior.
A control structure with one internal composition controller and one temperature controller provides effective control of both systems for both high and moderate conversion designs.
In basic systems and control theory, an effective controller must contain a model of the system it is controlling, i.e. the Process Model.
The situation could be improved by encouraging early diagnosis of the disease, by use of effective controller medication, and by increasing awareness and information among the general population; such measures could generate significant health care resource savings in the long-term.
This paper considers auto-tuning of simple lead-lag decoupler plus decentralized PI/PID controllers for effective control of two-input and two-output (TITO) processes.
The inclusion of wind energy system in DG, having high variability in its output power, results into a challenging task for the realization of an effective controller design.
A new method is proposed with which to design a class of robust fractional order controllers – which we denote as FPI controllers since they can be regarded as a generalization of standard PI controllers – for the effective control of water distribution in irrigation main canal pools characterized by time-varying dynamical parameters.
Recent physician surveys and pharmacy data suggest only 50-90% of eligible children are prescribed an effective controller medication, [ 20- 28] and up to a third of parents do not fill their child's prescription [ 20, 29].
