Intelligent prosthesis is a self-regulated robotic joint system. Iterative learning controller, ILC, is used to build up a decision-making expert system according to the repetition and periodicity in the motion of human prosthesis system. The historical data is used in ILC for optima control effect. As small error margin is permitted in prosthesis control, so the motion of human can be divided into...
This paper describes an active above knee prosthesis designed to compensate the movements of transfemoral amputees. Analyze the gait of transfemoral amputee wearing intelligent prosthesis. Though the prosthesis can change damping at different speed and gait, the gait of healthy side and affected-side is out of step. The disorder gait increase stress of residual limb. Using Vicon MX system captures...
A controller for a intelligent prosthetic knee which consists of four bar linkage mechanism with fixed pneumatic cylinder is presented. To detect human motion parameters, local sensor of goniometer and hall sensor are adopted. To obtain a displacement of the conical valve correspond to current speed, a knowledge base is established by ILC(Iterative Learning Control) algorithm. To validate the effects...
According to the repetition and periodicity of air conditioning system, a method of flexible iterative learning control based on the historical data is proposed and applied into the air conditioning system. The air conditioning system is repetitive and periodic with finite operation intervals, but there are some irregular uncertain factors, such as dynamic climate and other disturbances, so a flexible...
Basis on the analysis of the artificial limb knee joint and biped robot, the conception of dynamic limb prosthesis is introduced. Dynamic parts which are controlled by the information gathered from the body provide power to dynamic limb prosthesis. Dynamic limb prosthesis can simulate the movement of lower limbs which have hominine function and character. The model of dynamic limb prosthesis is designed...
In the foundation of conventional iterative learning control, regarding the flexible rule which performances duplication, periodicity and not determinism with the change of condition in the controlled process, the control decision-making questions of the flexible iterative learning control method was emphatically studied. By improving the algorithm of iterative learning control, the system will achieve...
