This work considers the modelling problem of the dynamics of overhead cranes with flexible cable and load hoisting or lowering during crane travel. The analysis includes the transverse vibrations of the flexible cable and trolley motion. A set of nonlinear ordinary differential equations governing behaviour constitutes a useful effort for analysis and control of many practical applications [1вЂ“3]. In modelling a DC motor connected to a load via a shaft, the general approach is to neglect the nonlinear effects and build a linear transfer function representation for the inputвЂ“output relationship of the DC motor and the load it drives [1,4]. This assumption is satisfactorily accurate

A SIMPLIFIED ANALYSIS OF NONLINEAR LONGITUDINAL DYNAMICS AND CONCEPTUAL CONTROL SYSTEM DESIGN ROBBIE BUNGE 1. Introduction The longitudinal dynamics of xed-wing aircraft are a case in which classical linearized If you are wondering why a 'Linear' model was chosen when this is a non-linear example, it is because this example is for non-linear geometry, not non-linear material properties. If we were considering a block of wood, for example, we would have to consider non-linear material properties.

synthesize the cloth deformation using the sensitivity analysis. Learning-based methods have also been popular for motion and control i.e. the reinforcement learning [31], [32], [33], [34]. In this paper, we present a new method of model reduction for nonlinear control systems. The goal is to develop an intuitively motivated and systematic procedure for construction of low-order models for complex high-dimensional nonlinear systems. The focus is on preserving those featuresof the dynamics which are most relevant to the control design, in a similar way to that in which standard

In mathematics, a dynamical system is a system in which a function describes the time dependence of a point in a geometrical space. Examples include the mathematical models that describe the swinging of a clock pendulum , the flow of water in a pipe , and the number of fish each springtime in a lake . The 4DOF model is coupled with a nonlinear suspension seat, and then a nonlinear seat-human system dynamic model is created in this research, as shown in Figure 6. The seat-human system model has five degrees of freedom: , , , , and ; the equilibrium position is the origin of the coordinate system; and the vehicle floor vibration displacement input is .

In this paper, the tracking control problem is considered for a class of uncertain nonlinear systems with infinite discontinuous points in the external disturbance. The extended state observerвЂ“based 2-degree-of-freedom control is used with one degree to estimate and cancel the вЂњtotal disturbanceвЂќ and the other to force the closed-loop system to have desired characteristics.

Quadcopter control is a fundamentally difп¬Ѓcult and interesting problem. With six de- grees of freedom (three translational and three rotational) and only four independent inputs (rotor speeds), quadcopters are severely underactuated. In order to achieve six degrees of freedom, rotational and translational motion are coupled. The resulting dynamics are highly nonlinear, especially after
