About

Alexandre Molter is a researcher whose work sits at the intersection of structural dynamics, robotics, and smart materials, with a particular focus on vibration control in flexible mechanical systems. His research has made meaningful contributions to the modeling and control of flexible-link manipulators, leveraging piezoelectric actuators and sensors to suppress unwanted vibrations that can compromise precision and performance in robotic applications. Among his most recognized contributions is a 2010 study on the simultaneous optimization of piezoelectric actuator and sensor placement combined with control design for flexible manipulators, which has garnered 31 citations. This work employed the State-Dependent Riccati Equation (SDRE) method and utilized finite element modal formulations grounded in Euler-Bernoulli beam theory, offering a rigorous and systematic framework for handling the complexities of nonprismatic link geometries. An earlier 2009 paper further established his foundational approach to tracking control in flexible robotic systems, integrating motor torques alongside piezoelectric actuation strategies. Molter's research is particularly valuable for engineers and scientists working on lightweight robotic systems, aerospace structures, and precision manufacturing, where structural flexibility poses significant control challenges. His mathematically grounded methodologies continue to inform ongoing research in smart structural control and flexible multibody dynamics.
