Further Information

The author's previous study proposed an efficient design method of time-varying gain type controller using the solutions of time-varying Riccati equations (TVREs) and its application to positioning control of time-invariant vibration systems. The responses of this method become similar to the responses of conventional nonstationary optimal regulators (NORs) which are effective controllers for positioning of vibration systems. This method generates the solutions of a TVRE and the responses of a controlled object simultaneously. The time-varying gains are obtained by real-time computations in actual implementations. This feature is convenient for the realization of some adaptive control. However, such a control method has not been fully addressed yet. This study proposes an adaptive nonstationary control (ANSC) method based on the feature of the previous study. We choose a cart with a time-varying vibration system whose natural frequency is time-varying as a controlled object example. The positioning and residual vibration reduction of the object are discussed in this paper. The effectiveness of the ANSC method is verified by simulations and experiments.
