In this chapter, we will focus on continuous-time, state-space models of the form ( x˙ = f (x) + G(x) · u (3.9) y = h(x) where: x ∈ Rn is the vector of state variables, u ∈ Rm is the vector of control input variables, y ∈ Rm is the vector of output variables, f (x) is an n-dimensional vector of nonlinear functions, G(x) is an (n×m)-dimensional matrix of nonlinear functions and h(x) is an m-dimensional vector of nonlinear functions.

For the quadrotor planning problem discussed in this paper, we choose a minimum-time cost function, that is: Planning in Information Space for a Quadrotor Helicopter in a GPS-denied Environment Ruijie He, Sam Prentice and Nicholas Roy In Proceedings of the IEEE International Conference on Robotics and Automation (ICRA 2008). Test flights of space vehicles are costly and take much preparation. As such, EV41 recently acquired a small research quadrocopter that has the ability to be a test bed for new control systems. This project focused on learning how to operate, fly, and maintain the quadrocopter, as well as developing and testing protocols for its use. Quadrotor Control: State-Space Model. March 11, 2019.

Quadrotor State Simulink Model Embeded Controller Command and Feedback Capture Figure 1. A Hummingbird quadrotor works with a Vicon motion capture system in the quadrotor test bed 2. Technical approach Fig. 1 illustrates the structure of the quadrotor test bed developed in this work. This test bed comprises a quadro‐

For the quadrotor to either control itself autonomously or to develop a high-level user interface for us to control Recall that state space models of systems are not unique; a system has many state space representations. Therefore we will develop a few methods for creating state space models of systems.

accelerometer model and actual measurements is shown. This new, drag-force-enhanced model is easy to use. The drag force constant can be estimated as a state in a ﬁlter driven only by inertial measurement unit (IMU) measurements, thus removing the need for experimental tuning, as in [12], or an expensive motion-capture system, as in [1].
