Advances in scheduling theory have given designers of control systems greater flexibility over their choice of timing requirements.
The research project described in this paper is an attempt to develop a methodological framework to support designers of control systems and human-machine interfaces, by conveying modem theories of supervisory/cognitive control and human-centred design principles.
The key benefit is that the designer of the control system can determine the attainable performance and hence the suitability of a control structure without a priori information about the closed-loop behaviour or the controller structure.
Although the general sliding mode control has the robust property, bounds on the disturbances and parameter variations should be known a priori to the designer of the control system.
In this formulation, the reliability of the structural system is represented in network form, allowing the designer to control global behavior of the system as a whole through the selection of a critical pathway through this network.
In addition, the FIFA platform allows the designer to control complexity and completeness of the analysis process.
Likewise, Stones found that the designers behind these miniature universes were attracted to the projects by the possibility of realising their personal visions in their entirety, with fewer compromises: "Small spaces allow a designer the kind of control you never get with huge places, because it always becomes too expensive," explains Stones.
Our results have important practical implications for designers of management control systems who elicit internal forecasts from managers.
It is commonly accepted that designers of supervisory control systems cannot comprehensively anticipate operators' information needs.
The designer of a digital control system must be mindful of the fact that the control algorithm is implemented as a software program that forms part of the control loop.
