These control systems are developed based on the quadrotor model derived in the System Modeling section, implemented in a simulated environment, and finally verified on an actual system. Lower level control systems will run at a high rate and control the quadrotor’s attitude. These controllers rely on the onboard IMU measurements.

The widely-used traditional quadrotor model (for example [4]–[11]) assumes that the signiﬁcant forces acting on the vehicle are gravity and the thrust produced by the rotors (see Figure 1). This assumption leads to a dynamic model for the quadrotor’s linear acceleration 2 6 6 6 6 6 4 u_ v_ w_ 3 7 7 7 7 7 5 = R. b I. 2 6 6 6 6 6 4 0 0 g 3 7 7 7 7 7 5 + 2 6 6 6 6 6 4 vr wq wp ur uq vp 3 7 7 7 7 7 5 2 6 6 6 6 Since a quadrotor is basically considered an unstable system with the characteristics of dynamics such as being intensively nonlinear, multivariable, strongly coupled, and underactuated, a precise and practical model is critical to control the vehicle which seems to be simple to operate. The nonlinear dynamic model of the quadrotor is formulated using the Newton-Euler method, the formulated model is detailed including aerodynamic effects and rotor dynamics that are omitted in many literature. Elruby et al. used software for estimating the moment of inertia. Their quad-rotor system is also a "+" configuration and uses the dynamic defined by Newton-Euler. The research results of flight Modelling and Linear Control of a Quadrotor The third and last method feeds back the same variables as the second method but uses a simpler model for the rotor dynamics.

As shown in Figure 3, the simulation software includes the quadrotor dynamics and the Guidance, Navigation and Control (GNC) module. The MA-OIF, MA-IE and OIF are all realised for comparison. 2019-01-11 model of quadrotor UAV equipped with gripper, which is followed by section ‘‘Designing of control architec-ture’’ in which designing of control architecture is pre-sented, and the ‘‘Dual control approach’’ and dynamic effects of gripper are also discussed in this section. In In this paper, the model of a quadrotor with quadrotor DJIF450 frame has been established using Newton Euler but with empirical parameter identification.
