Abstract

In the area of fault tolerant design and control, a measurement-based approach is considered to achieve control designs that preserve stability and performance under system failures. The problem involves the parametrization of input-output models in respect to the interest variables. The control design approach considered is based on frequency response measurements. Preliminary results show how classical stability margin based designs can be upgraded to a computer aided approach showing achievable designs, through the analytic determination of design surfaces that qualitatively and quantitatively display design trade offs. The design of coordinated control strategies according to the occurrence of events is also an important problem to be considered in this research. (AU)
