Estimation of Space and Time Shifts in Continuous 2-D Systems Using Instrumental Variable

Abstract: This paper develops an algorithm to estimate the space shift, time shift (or time delay), and parameters in a shifted continuous 2-D system described by a 2-D partial differential equation. Using the linear filter method, the simultaneous estimation of shifts and parameters is achieved. Also, the instrumental variable technique is used to remove the least square estimation bias, which is due to measurement noise. There are some methods to estimate the time shift in 1-D systems. However, no method has been prop… Show more

“…Thus, in particular, in Ding, Du and Li (2015) and Chen and Kao (1979), the parameters of 2D Auto-Regressive with Exogenous input (ARX) and Finite Impulse Response (FIR) models are estimated based on the Least Square (LS) method. In Ali, Chughtai and Werner (2010), Abedi (2013), andAbedi (2014a), the one-dimensional Instrumental Variable (IV) techniques are extended for identification of 2D systems. The parameter estimation of 2D systems with the state-space model is presented in Fraanje and Verhaegen (2005), Wang et al (2017), and.…”

“…Therefore, the parameter estimation should be computed recursively over time, as described in [ 13 ] in detail. Moreover, if the model is considered two-dimensional, the study by Shafieirad et al [ 14 ] can be helpful. In addition to the continuous models considered for epidemic dynamics, discrete models can also be used, which are discussed in [ 15 ] in detail.…”
