About
Alexandru Morar is a researcher specializing in advanced motion control systems, with a particular focus on stepper motor drives and adaptive control for robotics. His work bridges precision electromechanical design and robust control theory, addressing challenges in industrial automation and robotic manipulation. Morar’s most cited paper, “High Performance Microstepping Driver System based on Five-phase Stepper Motor (sine wave drive)” (2014, 5 citations), introduces a microstepping implementation for five-phase hybrid stepper motors that achieves standard full-step angles across multiple divisions—1, 2, 4, 5, 8, 10, 20, and 40. This innovation significantly reduces vibration and noise while improving control precision, offering practical benefits for applications requiring smooth, low-speed operation. In earlier work, “Simulation of the Local Model Reference Adaptive Control of the Robotic Arm with D.C. Motor Drive” (2010, 3 citations), Morar applied Lyapunov-based adaptive control to robotic arms with time-varying loads, ensuring global stability and robustness. By integrating adaptive control theory with motor drive systems, Morar contributes to more reliable and efficient automation solutions, making his research valuable for engineers and students exploring high-performance motion control and adaptive robotics.
