Abstract: This paper deals with the vibration control of a doubly
curved shell by Macro-Fiber Composite (MFC) piezoelectric actuator. The
driving force and bending moment formulas of MFC actuator are derived based
on the constitutive relations of the piezoelectric material and bending
deformation theory. The vibration of the doubly curved shell under fuzzy PID
control is simulated. Results show that using fuzzy PID controller can
effectively suppress the vibration of the system. Compared with classical
PID controller, the fuzzy PID controller shows better performance, faster
response and stronger robustness.
