- Abstract:
- Spinal traction system is a non-linear and time-varying control system. In order to control the trae-tion foree aeeurately, the PlD neural network algorithm is put forward in this paper. Firstly, the prineiple olthe spinal traetion control system based on PlD neural network algorithm is introdueed. Then the strueture andthe initial values as well as the learning rule of the weights of the PlD) neural network are analyzed. Finally,the PlD) neural network was eompared with conventional PlD control under the different control eonditions inthe experiments. The experimental results showed that the PlD neural network had the property of high foreetraeking aeeuraey and anli-intererenee ability, as well as the beler adaplability to parameler change, com-pared with eonventional PlD control. The feasibility and eorreetness of the spinal traetion system and the eon-trol algorithm were verified.
