Inverted spring pendulum driven by a periodic force: linear versus nonlinear analysis
نویسندگان
چکیده
We analyse the stability of the spring inverted pendulum with the vertical oscillations of the suspension point. An important factor in the stability analysis is the interaction between radial and oscillating modes. In addition to the small oscillations near the upper position, the nonlinearity of the problem leads to the appearance of limit-cycle oscillations of finite amplitudes.

Lyapunov - based PD linear control of the oscillatory behavior of a nonlinear mechanical system : the inverted physical pendulum with moving mass case ∗
This paper concerns active vibration damping of a frictionless physical inverted pendulum with a radially moving mass. The motion of the inverted pendulum is restricted to an admissible set. The proposed Proportional Derivative linear controller damps the inverted pendulum (which is anchored by a torsion spring to keep it in a stable upright position), excerting a force on the radially moving m...
متن کاملDesign of H-infinity Controller for A Linear Spring Connected Double Inverted Pendulum
A modified double inverted pendulum – modified by connecting the mass carrying the pendulum with another mass through a spring makes the general inverted pendulum become a more interesting problem. The system is defined as a linear spring connected double inverted pendulum as proposed by Hou et al. [1],[2]. The system is highly nonlinear and unstable. However, the system can be simplified to a ...

Double Inverted Pendulum is a nonlinear system, unstable and fast reaction system. Double Inverted Pendulum is stable when its two pendulums allocated in vertically position and have no oscillation and movement and also inserting force should be zero. The aim of the paper is to design and performance analysis of the double inverted pendulum and simulation of Linear Quadratic Regulator (LQR) con...
متن کاملCONTROL OF CHAOS IN A DRIVEN NON LINEAR DYNAMICAL SYSTEM
We present a numerical study of a one-dimensional version of the Burridge-Knopoff model [16] of N-site chain of spring-blocks with stick-slip dynamics. Our numerical analysis and computer simulations lead to a set of different results corresponding to different boundary conditions. It is shown that we can convert a chaotic behaviour system to a highly ordered and periodic behaviour by making on...
متن کاملA Switching Controller for the Stabilization of the Damping Inverted Pendulum Cart System
We present a switching approach for the stabilization of the strongly damped inverted pendulum cart system, provided that the pendulum is initialized inside of the upper-half plane, and the linear viscous force is known. The control strategy uses two stabilizing controllers. The first is a nonlinear controller, devoted to bringing the pendulum very close to its unstable equilibrium point. Then,...
