Abstract: A phase plane method is presented for the parameter identification
of strongly nonlinear systems. The phase trajectory equation is taken as the
mathematical model and the system parameters are identified by using the
optimum technique. The method can be applied to conservative and
non-conservative systems. The value ranges of the parameters are not limited.
All examples simulated by computer show that the efficiency and accuracy of
this approach are very good.
