Reliability-based control co-design of horizontal axis wind turbines

A Dendrite Net based decoupled framework for the reliability‐based control co‐design problem

“…Moreover, to exhibit the performance of DD model, KRG, RBF, RBFNN, and ANN are also utilized to approximate the state equation with the same samples. Three statistic criterions R 2 , relative average absolute error (RAAE), and relative maximum absolute error (RMAE) are used to evaluate the accuracy of those methods comprehensively, and those statistic criteria are calculated by Equation (23). where 𝑓 is the actual response of test sample; f denotes the mean of actual response.…”

“…Cui et al 22 conducted a comparative study of the simultaneous and nested formulations for RB-CCD, and presented a reliability-based codesign framework for linear quadratic problems with the double-loop method for reliability analysis. Cui et al 23 later provided detailed discussions about double-loop, single-loop, as well as decoupled-loop formulations for the RB-CCD problem in the horizontal axis wind turbine system. Lu et al 24 presented a cross-rate-based RB-CCD approach consisting of the CCD stage and a reliability assessment stage, in which a sub-optimization problem based on the cross-rate of the objective reliability index sample trajectory is designed to obtain the shifting vector.…”
