Visual Servoing Based Model Reference Adaptive Control with Lyapunov Rule for a Ball on Plate Balancing System

2018 International Conference on Intelligent and Advanced System (ICIAS), 2018
The 2 Degree of Freedom (DoF) ball balancer system is a highly nonlinear system where the position of the ball is controlled by controlling the two servo motors simultaneously. In general, conventional Proportional Integral Derivative (PID) controller and Proportional Velocity (PV) is used to control the location of the ball on a plate in $\pmb{X}$ and

An asymptotically exact stopping rule for the numerical computation of the Lyapunov spectrum

Chaos, Solitons and Fractals, 1996
Abstract It is in general not possible to analytically compute the Lyapunov spectrum of a given dynamical system. This has been achieved for a few special cases only. Therefore, numerical algorithms have been devised for this task. However, one major drawback of these numerical algorithms is their lack of stopping rules.

Lyapunov rule-based fuzzy control and chaotic anti-control for flexible joint system and analysis of chaotic signal existence effectiveness with experimental validation

2013 13th Iranian Conference on Fuzzy Systems (IFSC), 2013
This study proposes a novel chaotic anti-control for flexible joint system. The proposed controller is composed of a Lyapunov rule-based fuzzy control and chaotic anti-control for target tracking of the flexible joint manipulator. Chaotic signal is used to study the effect of anti-control to reduce the deflection of flexible joint system and control ...

Effect of adaptation gain and reference model in MIT and Lyapunov rule–based model reference adaptive control for first- and second-order systems

Transactions of the Institute of Measurement and Control, 2023
An adaptive control law encompasses a regulating control rule compensating for system dynamics variations by adjusting the controller characteristics to maintain the overall system performance. Recently, some techniques have been developed based on fundamental aspects of the adaptability of living organisms.

Lyapunov Spectrum and the Conjugate Pairing Rule for a Thermostatted Random Lorentz Gas: Numerical Simulations

Physical Review Letters, 1997
We report on the numerical computation of the Lyapunov exponents and the Kolmogorov-Sinai entropy for a three-dimensional, dilute, random Lorentz gas both in equilibrium and in nonequilibrium steady states. In our method the phase- and tangent-space dynamics are treated exactly.
