Pilot-Induced Oscillation Suppression by Using L1 Adaptive Control

الملخص EN

Despite significant technical advances, pilot-induced oscillation (PIO) continues to occur in both flight tests and operational aircrafts.

Such a phenomenon has led to significant research activities that aim to alleviate this problem.

In this paper, the L1 adaptive controller has been introduced to suppress the PIO, which is caused by rate limiting and pure time delay.

Due to its architecture, the L1 adaptive controller will achieve a desired response with fast adaptation.

The analysis of PIO and its suppression by L1 adaptive controller are presented in detail in the paper.

The simulation results indicate that the L1 adaptive control is efficient in solving this kind of problem.
