About

Clivaldo Oliveira is a researcher specializing in nonlinear dynamics, fractional calculus, and control systems for robotic manipulators. His work bridges theoretical modeling and practical control, addressing challenges posed by non-ideal excitation sources—a critical issue in real-world robotics where motors and actuators introduce unpredictable vibrations. In his most-cited paper (2012, 10 citations), Oliveira pioneered the application of Riemann-Liouville fractional calculus to model a two-link robotic manipulator, deriving fractional Euler-Lagrange equations that capture memory and hereditary effects absent in classical integer-order models. This foundational work opened new avenues for simulating complex robotic behaviors. More recently, Oliveira has focused on hybrid control strategies: his 2023 study (4 citations) integrates PID, LQR, and feedforward gains to stabilize a flexible-joint robotic arm under non-ideal excitations, while his 2022 work (2 citations) applies PID control to a double pendulum arm driven by a non-ideal source. Though his citation counts are modest, Oliveira’s contributions are technically significant, offering robust solutions for precision positioning in nonlinear, non-ideal environments—a niche with growing relevance in advanced manufacturing and autonomous systems.
