摘要：
Current identification is considered for unknown inputs on the basis of output signal measurements. The acquisition-system operator is estimated by the introduction of structural redundancy in the spatial domain. A method is considered for identifying a minimally redundant linear static system on the basis of preliminary transformation. The highest measurement accuracy is provided by preliminary quadratic transformation applied to the input signal in an additional channel in a minimally redundant acquisition system.
