A state-space model for a small radio-controlled helicopter in hover is developed. Linear estimation is used to identify parameters of the model. The parameter variances are used to develop an uncertainty description of the system. An LQG controller with setpoint tracking is designed and implemented on this system.

Autonomous helicopter flight represents a challenging control problem, with complex, noisy, dynamics. In this paper, we describe a successful application of reinforcement learning to autonomous helicopter flight. We first fit a stochastic, nonlinear model of the helicopter dynamics. We then use the model to learn to hover in place, and to fly a number of maneuvers taken from an RC helicopter co...

Introduction and purpose: Leishmaniasis are neglected diseases that are endemic in more than half of the provinces of Iran. The causative agent of this disease is Leishmania protozoa and its transmission to human is through the bites of phlebotomine sand flies. This study reviews the growth and development of Leishmania in the body of sand flies at the molecular level. Methods: In this study a ...
