Analysis and control of a helicopter model with unacceptable zero dynamics

https://doi.org/10.58571/CNCA.AMCA.2025.018

Resumen: The problem of the horizontal velocity control of a simplified helicopter model is addressed. This system has transmission zeros on the imaginary axis of the complex plane. This feature can significantly degrade control performance. In order to mitigate the effects of the almost non-minimum phase zeros, a control strategy based on classical techniques is proposed. The design relies on frequency-domain tools to ensure closed-loop stability and performance. Numerical simulations demonstrate the effectiveness of the approach in attenuating the influence of the transmission zeros and achieving satisfactory velocity regulation.
