Relay Feedback Identification of Anisochronic Models ? An Alternative Approach

Popis výsledku v původním jazyce

Models of dynamic systems containing both input and state delays were labeled as anisochronic due to non-simultaneous effect of state variables. These models have some practical and attractive features; especially they enable to capture the dynamics of systems with very high order, and mathematical models of many processes result in anisochronic form. In this paper, an engineering utilizable idea of the identification principle for anisochronic models based on limit cycle information obtained from relayfeedback test is investigated. Unlike conventional approaches connected with the frequency analysis of a plant transfer function, the proposed alternative methodology is based on computation with functional differential equation only. Plant parameters to be identified are obtained analytically. In addition, parameter estimation is also improved using autotune variable (ATV+) technique which required an additional delay element and two relay tests. Some numerical aspects of solution the
