Abstract
In today's industrial world, it is commonplace to use control in the design and operation of complex systems. However, severe limitations in potential performance are often present in such systems when large unexpected structural changes occur in the system, e.g. ‘conventional’ control schemes generally do not have the ability to control systems which are subject to unplanned extreme changes; we will call controllers which have this ability as being ‘intelligent’.
This paper introduces a controller, based on the results of [8], which has intelligent-like features. The controller is nonlinear and contains a switching device which applies a sequence of LTI controllers to the system, and which has the property that after a finite time (i.e. ‘learning’ time), switching ceases, resulting in the system being controlled by a LTI controller. The paper describes studies on implementing this class of controllers on ‘MARTS’, a highly interacting multivariable experimental hydraulic system; in particular, the paper shows how the new proposed ‘intelligent’ controller can successfully control MARTS, unlike conventional controllers, when a catastrophic change occurs in the system.
