Abstract: In this paper, fuzzy self-tuning controller is introduced first. The fuzzy model is built according to the experience of PID parameter tuning with fuzzy set theory. Parameter tuning is achieved by use of fuzzy ratiocination and decision according to actual response, which is applied for control towards robot. Mathematical model of two-link robot has been built as well as its geometric and dynamical equations through coordinate transformation and matrix operation. Finally, fuzzy PD controller with self-tuning method is applied to realize control towards robots. Simulation in Matlab has been carried out whose result shows that the control method proposed in this paper has better performance than the traditional ones.

Abstract: Design of manipulator control system for injection molding machine is raised in this paper. One servo motor and 32 pairs of IO of pneumatic actuators are applied to realize motion control towards manipulator. Functions such as precisely locating, multi-position start/stop and automatic mode operation are achieved through collaborative work of CPU and CPLD. Finally, the result indicates the control system is reliable and efficient.
