Linearized pendulum equation
Nettetsubstituting in these equations and simplifying leads to the equations that describe the motion of the inverted pendulum: These equations are nonlinear, but since the goal of a control system would be to keep the pendulum upright the equations can be linearized around. The generalized forces can be both written as potential energy and , Nettet24. jul. 2024 · The current work focuses on the motion of a simple pendulum connected to a wheel and a lightweight spring. The fundamental equation of motion is transformed into a complicated nonlinear ordinary ...

NettetGeneral Linearization Procedure I Why do we require that f(x 0;u 0) = 0in equilibrium? I This requires some thought. Indeed, we may talk about a linear approximation of any smooth function fat any point x 0: f(x) ˇf(x 0)+f0(x 0)(x x 0) f(x 0) does not have to be 0 I The key is that we want to approximate a given nonlinear system _x= f(x;u) by a linear … NettetThe animations below depict the motion of a simple (frictionless) pendulum with increasing amounts of initial displacement of the bob.
