ON THE LIMIT CYCLE PARAMETER IDENTIFICATION FOR ANISOCHRONIC MODELS
Original language description
Linear time invariant systems with delayed inputs have been intensively studied during last decades. Recently, models assuming delays also in state variables were investigated. A certain class of these models was labeled as anisochronic. These models have some practical advantages, e.g. they enable to capture the dynamics of systems with very high order. This contribution investigates an engineering utilizable idea of the identification principle for anisochronic models based on limit cycles. Unlike traditionally approach keeping to the frequency analysis of a transfer function, the proposed algorithm is based on computation with functional differential equation only. The results obtained are compared with the results derived earlier. Some computational aspects of the proposed method are discussed. The idea is verified by an academic example in which parameters of a high order system are assigned to a first order anisochronic model.

K identifikaci anizochronních systémů z mezních cyklů
Czech description
V poslední době jsou intenzivně studovány systémy a modely s vnitřními zpožděními. Takovéto modely dokáží vhodně aproximovat dynamiku soustav vyšších řádů. Příspěvek uvádí metodu k jejich identifikaci z reléového experimentu založenou na popisu systému včasové oblasti (narozdíl od tradičního postupu ve frekvenční oblasti). Získané výsledky jsou srovnány na ilustrativním příkladu s jinými metodami, odvozenými již dříve.
