| Sumario: | The Chua circuit parameter estimation problem is addressed in this paper. This circuit is algebraically observable and identifiable with respectto its two measurable voltages. This fact allows us to straightforwardly propose two linear estimators for recovering the unknown parameters,where the estimator gains are continuously adjusted by means of a gradient algorithm, until the estimated parameters converge to the actualvalues. The convergence of this method is demonstrated by using the Lyapunov method. |
