Abstract :
An algorithm for parameter estimation in a power converter-controlled DC motor drive system is proposed. The algorithm is based on the recently proposed framework of general hybrid orthogonal functions (GHOFs) for signal characterization in power electronic systems. The use of GHOFs allows parameter estimation directly in continuous-time models, bypassing the nontrivial problems of discretization which would otherwise arise in conventional techniques based on discrete-time models
