| 摘 要： | It is proposed a digital signal processing （DSP） controller used in the control system of six degree-of-freedom （DOF） giant magnetostrictive smart structure （GMSS）. Also are presented the controller design and its implementation, the embedded adaptive least mean-square （LMS） control algorithm and the real-time experiments of GMSS. Three programs are embedded in this controller. Of them are the adaptive LMS control algorithm and the other two which are used to search for the optimal values for the initial weight vectors. Moreover, the work flow and the control approach of the GMSS with the DSP controller are introduced. The experimental results indicate that the DSP controller has better control precision and real-time property, and the damping effect is up to 20 dB-30 dB.
