Implementation of An Embedded Hydraulic Controller WANG Chun-lin1 LI Zheng-xi2 TONG Chao-nan1 (1. Automatic Control Institute, University of Science and Technology Beijing, Beijing 100083,China； 2. North China University Of Technology) Abstract: An Embedded Hydraulic Controller is developed in the reconstruction of a domestic Iron and Steel Corporation. The hardware platform adopts industrial computer and I/O board which is made in Advantech Corporation ,Taiwan. The software is based on VxWorks, which is a powerful real-time operating system. In this paper, the design of Hydraulic Controller is given. In addition, the methods of implementing multiple tasks and precise periods are introduced.
