摘要：AbstractMutual adaptation is a stabilisation technique by which two unstable systems can reach stability via mutual interactions. It is a technique of great importance and advantage as it eliminates the necessity of a reference model for the systems to follow. The direct approach to mutual adaptation requires both systems to adapt concurrently. Unfortunately, this can lead to instability of the overall system. We propose here to use adaptive switching whilst systems mutually adapt wherein at any given interval of time only one of the systems is allowed to adjust. We provide empirical evidence that shows that such an approach allows broader applicability of the concept of mutual adaptation in that it mitigates a related orthogonality problem, allows a larger class of initial conditions, and improves the rate of convergence, all in the context of second-order systems.
