Performance improvement in decentralized adaptive control: a modified model reference scheme Academic Article uri icon

abstract

  • A modified decentralized model reference adaptive controller is proposed for a continuous time large scale system composed of N interconnected linear subsystems with unknown parameters. In the case where the high frequency gain of the transfer function of each of the isolated subsystems is known, the modified scheme can be used to improve the bad transient behavior that typically results from poor knowledge of the subsystem parameters. Each local adaptive scheme uses 'approximate differentiators', and so possible sensor noise amplification is expected to be an additional limitation of the proposed scheme.
