WANG Hong, YAO Xiong-liang, DAI Shao-shi. Control and mechanics analysis on SMA joint actuator[J]. 2007, (2): 28-30. DOI: 10.13873/j.1000-97872007.02.009.
The mechanics characteristic of a SMA joint actuator that is applied to micro biomimetic robot underwater is analyzed
and an experiment of the SMA actuator based on fuzzy control is completed.In the experiment
the physical characteristic of the SMA actuator is nonlinear
thermal hysteresis
time change and prodigious temperature effects.The SMA actuator works smoothly by applied the fuzzy control although it can bring a little over control.It is contented that the effect of the SMA actuator worked by fuzzy control.Therefore
the theory and applied value of the SMA actuator based on fuzzy control are remarkable.
