In this paper, an ANFIS+PID hybrid control policy has been addressed to control a 6-degree-of freedom (6-DOF) robotic manipulator. Then its error convergence has been also evaluated. The ability to formulate and estimate the system uncertainties and disturbances along with system dynamics and rejecting the disturbances effect are some advantages of the proposed method in comparing with the co...
In this research, an automatic control system is designed for landing of a small helicopter on a 4 DOF moving platform. The platform has three translational and one directional degree of freedom. The controller design approach is based on development of helicopter nonlinear dynamic model into the SDC (State Dependent Coefficient) form and real time solving of state dependent Riccati equation (S...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
A study of the kinematic characteristics for the five degree-of-freedom (DOF) spatial parallel micromanipulator is presented. The objective of this work is to introduce for the first time a structural and geometrical model of a novel five degree-of-freedom spatial parallel micromanipulator, the analysis of the effective and useful workspace of the micromechanism, present the obtained analytical...
Providing force and torque feedback in every degree of freedom of a haptic device can be complex and costly, often prohibitively so. Consequently, devices that reduce the number of actuators such as SensAble’s PHANTOM Omni, a 6-degree-of-freedom (DOF) positioning, 3-degree-of-freedom force feedback haptic device, have gained popularity. While these devices have been widely accepted, no previous...
The design and control of a 5 degree-of-freedom (DOF) haptic interface that provides accurate rendering of forces as well as a large range of motion is presented. We review a number of design approaches that have been considered in other haptic interfaces and the reasons for choosing a parallel mechanism for our design. The choice and motivation for the actuators, sensors, and materials used ar...
The goal of this paper is to describe the identification and modeling of a 3-degree-of-freedom (DOF) platform with a manipulator on top of it, which is magnetically levitated by 9 voice-coil actuators. This 3-DOF experimental setup is a pre-prototype of a 6-DOF magnetically levitated platform with manipulator in order to study combined control of both the platform and manipulator.
