Optimization of a Low Pass Filter Circuit Efficiency Using Computer Based Robust Engineering 2006-01-1418

Parameter and tolerance design are key steps in ensuring development of robust products. When input-output relationship is available in the form of a transfer function, the parameter design and tolerance design are carried out using computer experiments. In this paper transfer function of a filter circuit is used to demonstrate an approach to computer-based robust engineering. In the parameter design stage, the problem of optimizing the filter circuit efficiency is formulated as a non-linear optimization problem using the transfer function. For tolerance design stage, loss function is used to select the optimum tolerance values for the filter circuit components. The results obtained show an improvement in robustness over a previous study that used a heuristic approach.
