Abstract: This paper focuses on presenting a new identification algorithm to estimate the parameters and state variables for two-input two-output dynamic systems with time delay based on canonical state space models. First, the related input-output equation is determined and transformed into an identification oriented model, which does not involve in the unmeasurable states, and then a residual based least squares identification algorithm is presented for the estimations. After the parameters being estimated, the system… Show more

“…The proposed parameter estimation algorithms in this article are based on this identification model in (1). Many identification methods are derived based on the identification models of the systems [40][41][42][43][44][45][46] and can be used to estimate the parameters of other linear systems and nonlinear systems [47][48][49][50] and can be applied to fields [51][52][53] such as chemical process control systems. The process of calculating the estimateŝ(t) andb(t) of the weight vector and the bias term b through the NR-SVM algorithm ( 17)-( 27) is shown in Table 1.…”

“…Time delay is normal in engineering practices. e data of a dynamic system are usually collected by a sensor and then transmitted via a communication channel; they may encounter time-delay due to network congestion [25,26]. For the time-delayed model identification, Chen proposed a redundant rule-based off-line algorithm that can estimate the parameters and time delay simultaneously [27].…”

“…In [26], the problem of identification of typical error variable systems has been studied, a two-step identification method based on correlation functions has been proposed and parameter estimates of the model have been roughly calculated using the least squares and instrumental variables methods. In [27], a parameter and state variable identification algorithm based on a typical state-space model is proposed for two-input, two-output systems with time delays. In [28], an online identification method is proposed to estimate both the unknown system parameters and the unknown time delay.…”
