Smart Hydraulic System for Driving Robot Arm

A Digital-Driving System for Smart Vehicles

human driver or control the vehicle autonomously, they usually must make these decisions in real time with only incomplete information. So, human drivers still must maintain control over the vehicle. Advanced in-vehicle information systems (IVISs) endow vehicles with different types and levels of intelligence to complement the driver.2 Their introduction has allowed an almost symbiotic relation...

Hydraulic Motor Driving Variable-Pitch System for Wind Turbine

The present hydraulic variable-pitch mechanism of wind turbine uses three hydraulic cylinders to drive three crank and connecting rod mechanisms respectively; the blades are moved with the cranks. The hydraulic variable-pitch mechanism has complex structure, occupies a lot of space and its maintenance is trouble. In order to make up for the shortcomings of hydraulic cylinder variable-pitch syst...

The Smart Ogy Control of Two-Link Rigid Robot Arm

The smart OGY control method is proposed for two-link rigid robot arm. For this goal the Bifurcation diagram should be applied for acceptable wide range of the input amplitude. Then by using the robot arm in a chaotic amplitude range and Poincare section, the UPO's will be found. After that, the OGY rules are defined for each UPO's and the maximum changed value of amplitude for each UPO's, whic...

The reduction coefficient of PID controller by using PSO algorithm method for Flexible single-arm robot system

This study on the design of PID controllers for flexible single-arm robot system optimizationPSO method is focused so that the coefficients of the PID controller are reduced. In this study,PID controller and PSO algorithm have been described and then by using MATLAB, PIDcontrol was simulated. Then by PSO algorithm, attempts to reduce the PID coefficients are givenby simulation. Finally PID coef...
