Abstract
A parameter estimation device includes an input signal detecting means 3 that detects an input signal inputted to an object system 1 expressed by an equivalent circuit model 5A containing at least an integrator element COCV, an output signal detecting means 2 that detects an output signal outputted from the object system, an output differentiating means 4 that differentiates the output signal to obtain and output an output differential signal, a modified equivalent circuit model 5B where respective elements of the equivalent circuit model 5A are changed to non-integrator elements in such a way that the output when the input signal is inputted becomes an output differential signal, and an element parameter estimating means 5 that estimates the parameters corresponding to the respective elements based on the modified equivalent circuit model by using the signals.
