Optimal design approach towards standard electromyography (EMG) controlled hand prosthesis system

Prosthesis is an artificial device that is the substitute of a missing body part like hand and Dexterity is the grace and ease of using the hands. Invention of the myoelectric prosthesis was the most exciting development in prosthetics in recent times. Myoelectric controlled Prosthetic Hand is very significant for handicapped person. This paper deals with an approach to achieve optimum condition of a standard myoelectric hand prosthesis system. The standard transfer function of the system is chosen to achieve the optimized response by increasing the system stability and minimizing the system error. The optimal condition has been gained by using an appropriate PI controller. Computational approach towards stability is involved here with proper and accurate optimization. Particle Swarm Optimization (PSO) technique is also introduced to eliminate the system error further.
