“…Nevertheless, the parameters of the three terms cannot be changed after they are determined, which has an adverse effect on controlling nonlinear systems. Therefore, combining classical PID with fuzzy control, the fuzzy PID can adjust parameters timely according to the real-time response of the operating system [16]. The control principle is shown in Figure 18.…”

“…To reduce response time, Rasid et al [15] proposed a piezoelectric multi-layer actuator instead of electrostatic actuators to drive a micro-lens for imaging applications. Sumit et al [16] studied the static displacement of a piezo actuator made of PZT-5H under high input voltage, and the result is helpful for designers to control the shape and vibration of bending piezo actuators. Though piezoelectric ceramics usually have strong hysteresis effects and require high driving voltage, the geometry of the piezoelectric element has a beneficial impact on the actuation.…”

To align a pair of optical fibers, it is required that the micro actuators used be small and have the characteristics of high accuracy and fast response time. A trapezoidal piezoelectric bimorph actuator was proposed for pushing and pulling an optical fiber. Based on a mathematical model and finite element model established in this paper, we analyzed the output displacement and output force of the proposed trapezoidal piezoelectric actuator under the influence of structural parameters. Since the piezoelectric bimorph actuator had a hysteresis effect, we applied particle swarm optimization to establish a Prandtl–Ishlinskii (PI) model for actuator and parameter identification. Then, two control methods, namely feedforward control considering hysteresis effects and fuzzy proportional-integral-derivative (PID) control employing feedback, were proposed. Finally, a composite control model combining the two control methods with fewer tracking errors was designed. The results show that the output displacement of this actuator is larger than that of a rectangular one. Additionally, the fuzzy PID control has a lower response time (15 ms) and an overshoot (5%).

“…Continuous piezoactuator with multiple electrodes is preferred over numerous segmented piezoactuators to achieve the target profiles [20]. Both piezoceramic and single crystal actuators show nonlinear behaviour at high electric fields [21][22][23][24][25][26][27][28][29]. Most of the studies available in literature [30][31][32][33] have used variable piezoelectric strain coefficient (function of strain or electric field) to simulate the nonlinear behaviour of piezoelectric actuators.…”

In this paper, experimental study for shape control of silicon mirror is done by nonlinear piezoceramic actuator. A piezoelectric unimorph-based silicon mirror (PUSiM) is fabricated using APC 850 piezoceramic for shape control analysis. The piezo response function of all the actuators and profile of PUSiM are measured by confocal sensor at various applied electric fields to verify the nonlinearity of piezoceramic actuator. For comparison, electromechanical coupled finite element model of PUSiM is developed. Recently proposed iterative piezo response function-based optimization is used to calculate the electric field of piezoceramic actuators to achieve the target elliptical profile of PUSiM. At optimum voltage the achieved profile of PUSiM is quite close to the target elliptical profile with 193 nm root-mean-square error. Knowing the nonlinearity inherent in the piezoceramic actuators at high voltages the proposed measurement technique is a way forward for the shape control of structures and deformable mirrors.

“…The desired shape of the smart structure is not obtained at optimum electrode potential if PRF-based formulation is used to optimize the electrode potential of the nonlinear piezoactuators. A number of studies are present in literature [43,[48][49][50][51][52][53][54][55] which show that the behavior of some piezoelectric materials specially lead zirconate titanate (PZT) type piezoelectrics are nonlinear with the applied electric field. Due to this reason, optimization using PRF is not feasible to determine the electrode potential of nonlinear piezoactuators.…”

Shape control of complex structures by optimizing the electrode potential is not achievable directly by analytical solutions and piezo response function base-optimization techniques due to the nonlinear response of piezoactuators. In the present work, a metaheuristic iterative piezo response function (iPRF)-based optimization technique is developed to achieve the arbitrary shape of piezoelectric unimorph using nonlinear piezoactuators. In this regard, a piezoelectric unimorph (PU) is fabricated using APC 850 piezoactuator to verify the nonlinear response in bending mode and nonlinear analytical model of PU. After verification, length of the inactive layer and number of piezoactuators in PU are modified to study the shape control. iPRF-based technique is used for the optimization of electric potential to achieve the target shape of modified piezoelectric unimorph (MPU) with varying piezoactuators. The results of iPRF-based technique are compared with the results of simulated annealing-based direct optimization technique. Unlike simulated annealing-based direct optimization technique, prior knowledge of nonlinear coefficients of piezoactuator is not required in iPRF-based technique. Optimum values obtained from both the direct nonlinear solution- and iPRF-based optimization methods are same for all MPUs. Furthermore, the number of iterations of iPRF-based optimization approach is not affected by the number of piezoactuators used to achieve the desired shape.
