✦ Synopsis

In this paper, "least squares" and recursive methodsfor simultaneous idemt$ication of four nonminimum phase linear, time-invariant FIR systems are presented. The methods utilize the second-and fourth-order cumulants of outputs of the four FIR systems of which the common input is an independent, identically distributed (i.i.d.1 non-Gaussian process. The new methods can be extended to the general problem of simultaneous iden@cation of three or more FIR systems by choosing the order of the utilized cumulants to be equal to the number of systems. To illustrate the eflectiveness of our methods, two simulation examples are included.

Conventional parameter estimation approaches fail to identify linear systems operating in closed loop when both input and output measurements are contaminated by additive noise of unknown (cross-)spectral characteristics. However, even in the absence of measurement noise, parameter estimation is inv

This paper presents a function-oriented system analysis method that gains knowledge about properties of technical systems, including system capabilities that can appear as sources of incipient failures. Such failures have a significant role in connection with process control systems, since they can
