Altitude Control of Small Helicopters using a Prototype Test Bed
نویسندگان
چکیده
In this paper we present an experimental test bed for the development and evaluation of control systems for unmanned helicopters. The test bed consists of a small unmanned helicopter, mounted on a flying stand that permits all possible movements but prevents the helicopter from damaging or crashing. A fuzzy controller is developed in MATLAB and tested in the helicopter using the test bed. The controller is able to perform hovering and altitude control. Experimental results are presented for various test cases.

Correlating Kinematics & Control Inputs on Small-Scale Helicopters
We present a time-domain technique for correlating the control inputs given to hovering, small-scale helicopters with their corresponding accelerations. The resulting correlations give a simple plant model that can be used for proportional-integral-derivative (PID) controller gain tuning, helicopter trimming, and simulations to test low-level controllers. We have collected our data in the Auton...
متن کاملAutomatic Landing of Small Helicopters on 4 DOF Moving Platforms
In this research, an automatic control system is designed for landing of a small helicopter on a 4 DOF moving platform. The platform has three translational and one directional degree of freedom. The controller design approach is based on development of helicopter nonlinear dynamic model into the SDC (State Dependent Coefficient) form and real time solving of state dependent Riccati equation (S...
