This video talks about the quadrotor dynamics/physics for CMSC828T: Vision, Planning and Control in Aerial Robotics course at the University of Maryland, Col 4. Basic Dynamic Model of a Quadrotor.

### Oxide Computer Company: On the Metal: Star Simpson The dynamic model of the quadcopter is an open loop and closed loop control is a preferred. method for any design because the system records the output instead of the input and. modifies its output per a preferred condition. THE DYNAMIC MODEL In order to define the dynamic model of the quadrotor, an inertial reference frame Fw and a frame Fb rigidly connected with the quadrotor body are assigned. The axes xb and yb of Fb are directed along the arms connecting the body with propeller 1 and 2 respectively, while zb is oriented to complete the frame, see Fig. 1. In the first part, dynamics model is developed using Newton-Euler formulation, and obtained equations are verified in comparison with Lagrange approach. Consequently, a nonlinear control strategy based on dynamic model is used in order to control the position and attitude of the quadrotor. QUADROTOR SYSTEM MODEL >D The development of a suitable attitude controller for the quadrotor prototype required an accurate dynamic model to be developed.

i Using RNNs, it is possible to learn a dynamic model of a quadrotor from observations , . In an MS prediction scenario, the input to the RNN is a sequence of the motor speeds and the RNN generates the quadrotor states. Therefore, each training instance is a tuple of two equal-length time-series, an input, which is the motor speeds, We develop a multi-step motion prediction modeling method for dynamic systems over long horizons using deep learning. Building on previous work, we propose a novel hybrid network architecture, by combining deep recurrent neural networks with a quadrotor motion model created using classic system identification methods.

In summary, we mainly use the quadrotor for two kinds of applications, a) reinforcement learning, b) model-based control, such as MPC. For a), please refer to quadrotor_env. Quadcopter Dynamics We will start deriving quadcopter dynamics by introducing the two frames in which will op-erate. The inertial frame is deﬁned by the ground, with gravity pointing in the negative z direction. The body frame is deﬁned by the orientation of the quadcopter, with the rotor axes Newton’s and Euler’s laws. A linearized version of the model is obtained, and therefore a linear controller, the Linear Quadratic Regulator, is derived. After that, two feedback linearization control schemes are designed. The ﬁrst one is the dynamic inversion with zero dynamics stabilization, based on Static Feed- Quadrotor control requires an accurate model of the system.
