In this paper, a simple structure design with arbitrary motion/force scaling to control teleoperation systems, with model mismatches is presented. The goal of this paper is to achieve transparency in presence of uncertainties. The master-slave systems are approximated by linear dynamic models with perturbed parameters, which is called the model mismatch.(More)
This paper presents an intelligent system to translate Arabic natural language to Arabic sign language based on knowledge base and image processing. This system was designed to help hearing impaired for improving their connection with hearing world and acquiring new concepts. The system plays a role for assisting teachers in sign language domain. Of the(More)
Time-delay in communication channels and uncertainty in different parts of the teleoperation systems are considered to be a major group of destructive factors in stability and performance of these systems. This paper suggests a new method based on a Linear Matrix Inequality (LMI) approach to establish robust PID controllers. The stability and performance of(More)
