Embodiment 2

[0060] The structure and method steps of this embodiment are the same as those in Embodiment 1. The macro drive system of each axis is electro-hydraulic servo drive. Features such as light weight and good acceleration. The micro-drive system of each axis is precisely driven by piezoelectric ceramics. Electroceramic has small volume, high resolution and easy control; compared with series mechanism, parallel mechanism has high structural rigidity and load bearing Features such as strong capability, high precision, and compact structure have been more and more widely used. This invention combines the unique advantages of hydraulic servo technology and piezoelectric technology and applies it to parallel mechanisms to achieve large stroke and high-precision control. The macro-micro hybrid drive parallel mechanism, control system, and sensor acquisition system form a complete measurement and control system, which can control the pose of the macro-micro hybrid drive parallel mechanism...

Description

technical field [0001] The invention relates to the field of measurement and control systems for parallel mechanisms, in particular to a measurement and control system for parallel mechanisms driven by macro-micro hybrids and a control method thereof. Background technique [0002] With the continuous development of modern science and technology, in various fields such as precision machining and precision measurement, aerospace technology, biomedical engineering, and microelectronics engineering, higher requirements are put forward for the stroke and accuracy of positioning devices. Therefore, large-travel high-precision positioning technology plays a key role in modern science and technology, and is also one of the research hotspots in the field of precision engineering in recent years. However, large travel and high precision are contradictory. An effective solution today is to use macro / micro hybrid servo drive technology, which has high precision and high resolution, has...
