Control System for Multi-Input and Simple-Output Piezoelectric Beam Actuator Based on Macro Fiber Composite

A control system for a piezoelectric beam actuator, which had one or two inputs, was subject of numerical and laboratory research. The actuator prismatic shape with rectangular cross-section consisted layer carrying substrate made from PCB-FR4 patches Macro Fiber Composite P1 type. MFC were glued on both sides the substrate. An article presents comparison quality signal (one-input actuator) signals (two-input actuator). application two-input led to reduction voltage compared one-input actuator. decrease in maximum approximately 30% 39% conducted experiments. causes an overshoot value limit leads greater
