Developement Of A Batch Mode For Conduit And Its ... - Cal Poly

This rating system was used in conjunction with flight test data using a variable
stability aircraft to create a group of handling qualities specifications, in which
measurable parameters of an aircraft’s performance could be used to predict pilot opinion
of the handling of the aircraft.
By incorporating handing qualities specifications into the design of an aircraft, it
will most likely have good handling qualities. However, there are certain consequences
involved when doing so. The process of evaluating a single spec (specification) is time
consuming, much less several specs, resulting in possibly long design cycles.
Furthermore, the presence of multiple competing specs adds another level of complexity
to the problem. Another difficulty is that if the model, control architecture, or any
component of the system changes, the entire process must be repeated. Finally, while a
system might be created that meets all necessary specifications, chances are that it is not
optimal. Trade-off studies may be developed as a means to make best use of the
available control authority, however, this can be time consuming.
In response to these difficulties, a multi-objective optimization program, called
CONSOL-OPTCAD, was developed at the University of Maryland. This program
interfaced with the MATLAB environment, using MATLAB’s system modeling
capabilities. A model following control system was developed for the UH-60, using the
CONSOL-OPTCAD multi-objective optimization to optimize the control system based
on several handling qualities specifications. In doing so, the capability of the
optimization routine was demonstrated. However, its use was still limited in that the
UH-60 problem was hard-wired into CONSOL-OPTCAD. Modifying the code to work
with a new problem involved several months of work. A variant of this effort was thus
