چکیده

In the paper, the differential equations of the controlled pneumatic actuators as a part of simulator for training drivers of freight vehicles based on 6-DOF Stewart Platform are presented. The sliding-mode control strategy is proposed and studied by simulations. The experimental results for the existing on-off logical control algorithm are given, showing potential advantage of the sliding-mode controller for tracking fast reference signals.

Flatness-based control of a two-degree-of-freedom platform with pneumatic artificial muscles

Abstract—Pneumatic artificial muscles are a quite interesting type of actuators which have a very high power-to-weight and power-to-volume ratio. However, their efficient use requires very accurate control methods which can take into account their complex dynamic, which is highly nonlinear. This paper consider a model of two-degree-of-freedom platform whose attitude is determined by three pneum...

Spherically actuated platform manipulator

This article presents the inverse and forward pose and rate kinematics solutions for a novel 6-dof platform manipulator, actuated by two base-mounted spherical actuators. The moving platform is connected to the fixed base by two identical SPU serial chain legs. The S-joint is active, and the remaining two joints in each chain are passive. An analytical solution is presented for the inverse pose...
