Many studies have demonstrated the utility of surface dielectric barrier discharge (SDBD) plasma actuators driven by different voltage waveforms for airflow control. In this paper, a new dual-power supply voltage consisting of ac high voltage with a superimposed positive or negative pulse bias voltage is applied to a two-electrode structure SDBD actuator to compare the actuator performance with that...
This paper proposes a combined method for motion/force tracking control of a class of Lagrange mechanical systems by using cascaded methods and backstepping techniques. This paper first transforms error dynamics between the kinematic system and the desired trajectories into a cascaded system consisting of two subsystems and an interconnection function, then, designs virtual controllers for the kinematic...
The aim of the paper is to develop a upper limb rehabilitation robot system (DPRs) capable of making both patient assessment and robot-aided assessment. Using the rehabilitation robot system, patients can repeatedly train in high efficiency and can replicate many of the human training. In the paper. First a diamond rehabilitation robot(DR)was designed and its model was also given. Then an evaluation...
Force information in virtual space is important and often required for tele-operation, training, amusement, design supporting, and other virtual reality systems. The application of passive-type force display and rehabilitation system is desirable for its high safety. However, there are some directions and link positions for which it is difficult to display the force using only passive elements. To...
We developed a compact and low-cost quasi-3-DOF rehabilitation system ldquoHybrid-PLEMOrdquo for upper limbs of stroke patients. Hybrid-PLEMO has 2-DOF force feedback function in working plane, its working plane can be adjusted the inclination, and it can be switched between active type and passive type. However, there are some directions and link positions which are difficult to display the force...
Several 2-DOF rehabilitation robots for upper limbs have been proposed so far, and clinical effectiveness was reported in several studies for the aged people or patients with stroke. We developed the quasi 3-DOF rehabilitation system ldquoHybrid PLEMOrdquo which has 2-DOF force-feedback function in working plane but its working plane can be adjusted the inclination. Hybrid-PLEMO is a compact, low-cost...
