A 3 DOF Piezohydraulic Parallel Micromanipulator
نویسندگان
چکیده
The paper presents a new parallel micromanipulator that is composed of three piezohydraulic actuation systems. The basic elements of the actuation system are a piezoelectric actuator, a bellows and hydraulic oil. The use of the flexible bellows results in a new type of parallel structure, where the joints are integrated into actuator links. The joint-free tripod-like micromanipulator is controlled using a real-time control software that is based on a multi-level architecture. Control is organised in four levels for non-linearity compensation, position feedback control, supervision and tackling of automatic operations. The presented micromanipulator provides an exceptional combination of submicrometer resolution, large work space, miniature size and advanced control.

Position control of a 3 DOF piezohydraulic parallel micromanipulator
This paper focuses on the open-loop and closed-loop position control of a tripod-like joint-free parallel micromanipulator that is composed of three piezohydraulic actuation systems. The micromanipulator is controlled in open-loop using a general inverse kinematics model presented earlier for a tripod manipulator having ball and pin joints. Open-loop control is sufficient in many applications b...
