-In this paper, we present modeling and control of a simulated flight of a mini helicopter using matlab/simulink. First, we are interested in the analysis of dynamic modeling of helicopters. Indeed, based on the hypotheses established beforehand, we obtain some simplifications of the model for the cases of low-speed flight and thus to a stationary flight. Therefore the full model could be simplified by a three-step approach, to get the mathematical model of our mini helicopter. Second, we conceive control laws for the established dynamic model using several techniques of control. So we start by an open loop control via a joystick, to validate the response of the model to the inputs commands, given by a user. After, we design a PID controller to stabilize the system on a stationary flight. Then, we try to apply a nonlinear control for the helicopter such as the linearizing control. Finally, an optimal linear control is designed based on the Kalman observer. The use of this study is giving a basic simulation platform for mini helicopter, and compares different control laws results.
