adaptive integral backstepping的用法和样例：
- The adaptive integral method (AIM) combined with a novel mesh neighbor (MN) preconditioner is applied to the scattering analysis of 3D PEC structures.
- For mechanical servo system,a novel servo controller based on integral backstepping scheme was presented,the controller has strong robustness to external disturbance and system parameter changes.
- Then, by using integral backstepping approach, the output-feedback stabilization control is constructively designed so that all the signals in the closed system are asymptotically convergent.
- The proposed new VFC-based adaptive integral is advantageous over the conventional implementation in measurement time, effective noise bandwidth and alternative frequency attenuation.
