Error Produced Because of the Unacuaracy in the Parameters Estimation in an Inverse Volterra Open Loop Control for Duffing Oscillators

The open loop control using the inverse Volterra system is very attractive as the system is supposed to be transformed into a system of unity gain and possessing an infinite bandwidth. However, the proper function is always limited to an accurate model of the system. This work presents an analysis of the error and stability produced because of the inaccuracies in the parameter estimation. From the work done here it is possible to have a proper criterion to evaluate if this kind of control is adequate for a particular control application.
