“…In this work, we propose a methodology for the actuator and sensor position and sizing optimization, based on maximization of dissipation of the energy control (Li et al, 2002). This procedure takes into account the actuators and sensors mass and stiffness and their effect on the mechanical behavior of the structure.…”

“…In order to eliminate this dependence, we assume that the initial state of z satisfies λ are larger than the others, because it is expected that the lowest frequency modes are more easily excited by the rigid body motion (Li et al, 2002). Therefore, we obtain an objective function (Truhar, 2004),…”

“…Locations of piezoelectric sensors and actuators may influence the controllability and observable properties of a system, and have significant influence on the control performance. There has been numerous research for the optimal placement of actuators and sensors for smart structures [21][22][23][24][25][26][27][28]. A typical solution to the location problem is found through a search procedure, for large number of locations, the search is overwhelming and time consuming and not necessarily the optimal solution.…”

Space manipulators are flexible structures. Vibration problem will be unavoidable due to motion or external disturbance excitation. Model based control methods will not maintain the required accuracy because of the existence of nonlinear factors and parameter uncertainties. To solve these problems, fuzzy logic control laws with different membership function groups are adopted to suppress vibrations of a flexible smart manipulator using collocated piezoelectric sensor/actuator pair. Also, dual-mode controllers combining fuzzy logic and proportional integral control are designed, for suppressing the lower amplitude vibration near the equilibrium point significantly. Experimental comparison research is conducted, using fuzzy control algorithms and the dual-mode controllers with different membership functions. The experimental results show that the adopted fuzzy control algorithms can substantially suppress the larger amplitude vibration; and the dual-mode controllers can also damp out the lower amplitude vibration significantly. The experimental results demonstrate that the proposed fuzzy controllers and dual-mode controllers can suppress vibration effectively, and the optimal placement is feasible.

Optical Fourier surface is a unique patterned optical surface containing the precise sum of sinusoidal waves, each with a well‐defined spatial frequency and amplitude. It can manipulate the desired diffracted light field through its Fourier transform, which brings a straightforward mathematical method for designing complex diffractive optics. However, the fabrication techniques typically have the drawbacks of low efficiency, limiting the large‐scale industrial application of optical Fourier surfaces. This study presents a powerful approach, the multi‐frequency vibration cutting (MFVC), to enable the high‐efficiency fabrication of optical Fourier surfaces. A specific optical Fourier surface consisting of arbitrary frequency components of linear gratings has been fabricated on metallic surfaces using MFVC. Due to the capacity of multicomponent gratings in coupling red, green, and blue lights at the same incident angle, the RGB true color has been prepared. The additive and subtractive principles of mixing the three primary colors are demonstrated. The former relies on the light dispersion induced by grating diffraction, while the latter is based on the light absorption induced by the subwavelength grating‐coupled surface plasma polarization (SPP). The experimental results of authentic structural true color on the aluminum surface verify the efficacy of MFVC in the fabrication of optical Fourier surfaces.
