We examine whether the macroscopically measured diffusion rate in the chaotic region of a time-perturbed classical pendulum depends on the value of the maximal Lyapunov characteristic number, λ. In this respect we calculate the functions λ(l),w(l), λ( ) andw( ), where l denotes the physical length of the pendulum, the strength of the perturbation andw the width of the stochastic layer around th...

Sliding mode control is quickly becoming a popular research ...eld due to the several favorable qualities, including robustness. Linear quadratic control has been one of the more popular and more traditional control techniques, partially due to the ease of implementation and its optimality quality. In this paper, we provide an introduction to sliding mode control. A technique is suggested to al...

Intermittent predictive pole-placement control is successfully applied to the constrained-state control of a prestabilised experimental inverted pendulum.

berthing force is a critical dynamic lateral force in the design of berthing structures, having equal relevance when compared to seismic forces. besides, the construction cost of berthing structures is very high which can be optimized by calculating precise design berthing energy on fender and selecting optimum fender system. in the present study, design berthing energy of bulk carriers having ...

Reinforcement learning has been active research area not only in machine learning but also in control engineering, operation research and robotics in recent years. It is a model free learning control method that can solve Markov decision problems. Q-learning is an incremental dynamic programming procedure that determines the optimal policy in a step-by-step manner. It is an online procedure for...

this paper presented comparison of the time specification performance between two type of controller for a Double Inverted Pendulum system. Double Inverted Pendulum is a non-linear ,unstable and fast reaction system. DIP is stable when its two pendulums allocated in vertically position and have no oscillation and movement and also inserting force should be zero. The objective is to determine th...

This paper investigates the implementation of a pendulum-driven cart-pole system through wireless networks. The system is underactuated since the only control input is the motor which drives the pendulum movement while the cart has free movement wheels. An onboard client PC controls the torque to the motor, whilst a host PC monitors progress and controls the demand to the motor. The two PCs hav...

This paper describes the swing-up and stabilization of a cart–pendulum system with a restricted cart track length and restricted control force using generalized energy control methods. Starting from a pendant position, the pendulum is swung up to the upright unstable equilibrium con5guration using energy control principles. An “energy well” is built within the cart track to prevent the cart fro...

The aim of this study was to compare the kinetic and kinematic characteristics of plyometric drop-jump and pendulum exercises. Exercises were filmed (100 Hz) from the sagittal view and manually digitized; the data were smoothed and differentiated using cross-validated quintic splines. Ground reaction force data were sampled using a Kistler force platform sampling at 500 Hz. Differences between ...

Algorithms which guarantee to find globally optimal trajectories by covering a hypervolume of state space become infeasible in high dimensions. We have developed an algorithm which generates locally optimal trajectories without covering a hypervolume which only requires polynomial memory and time. Even though the algorithm does not guarantee a globally optimal trajectory in a deterministic mann...
