  • Computer control of a powered two degree freedom reciprocating gait orthosis
  • Published at:Not Found
  • The design of a motion control system for a powered reciprocating gait orthosis is considered. Models for the orthosis are obtained using least squares identification. The control system design is based on pole-placement techniques and a restricted Youla parametrization of the controller. Experimental results are included.

  • Modeling and Control of Mobile Robots
  • Published at:Not Found
  • Mobile robots is a relatively new research area that is normally considered from several different perspectives mainly, engineering and computer science levels. This paper deals with the engineering level of mobile platforms; i.e. the physical, hardware and mechatronic levels of mobile platforms, and presents complete models for the main hardware components of mobile platforms. The presented models can be used for simulation and control of mobile platforms, and they take into account the hardware limitations, friction force and the topography of the environment for out door navigation.

  • Friction identification in mechatronic systems
  • Published at:Not Found
  • Since no universal friction model exists and the practical measurement of friction is not straightforwad, this paper presents an experimental method of identifying friction in mechatronic systems. Friction is prehaps the most important nonlinearity that is found in any mechatronic system of moving parts and influences the system in all regimes of operation. For the purpose of improving the performance of mechatronic systems and solving their servo problem, a better understanding of friction behavior in its two basic regimes is needed. In this paper, the two basic friction regimes, viz., presliding with its hysteresis behavior, which is predominantly position dependent, and gross sliding, which is predominantly velocity dependent, are well exposed and identified.
