Tendencies and prospects of designing of control systems of robots with manipulators of parallel kinematics |
V.M. BUYANKIN
Now in a science and the industry there were robots manipulators with parallel kinematics. As a whole, the manipulators constructed on the basis of parallel mechanisms, possess a great number of degrees of mobility in comparison with traditional robots-manipulators and provide more high efficiency, reliability and accuracy. Mechanisms from parallel kinematics have the raised rigidity of a design, accuracy of moving. However in the multisection robot-manipulator as a result of moving of sections of the manipulator their moments of inertia, and also the moments of inertia of platforms change rigidity of bars. Presence of a dry and viscous friction in hinges of the manipulator which have the indistinct mathematical description, can lead to its deterioration static and dynamic characteristics, including, to fluctuations of a design of the manipulator. It is necessary to develop new methods for indemnification of these lacks adaptive neurocontrol with indistinct logic on the basis of digital watching electric drives.
Keywords: Robot, manipulators, parallel mechanisms, adaptive neurocontrol, fuzzy logic, digital servo actuator.
