About

Alexander Stotsky is a control systems engineer whose research spans adaptive control, mobile robotics, and nonholonomic systems, with particular expertise in developing robust algorithms for complex mechanical platforms. His early work in the 1990s laid important theoretical foundations for robot control, most notably his 1993 paper on adaptive trajectory and force control for constrained robot manipulators (33 citations), which proved asymptotic stability and force convergence while circumventing restrictive solvability conditions that had limited earlier approaches. Alongside this, his 1992 study on speed gradient adaptive control algorithms (14 citations) provided a unified framework for evaluating adaptive methods across mechanical systems. Stotsky's research evolved significantly toward mobile robotics, where he made substantial contributions to car-like robot control. His influential 2002 series of papers introducing the "virtual vehicle" approach (collectively accumulating over 75 citations) demonstrated model-independent, disturbance-robust path tracking algorithms validated through dynamic modeling. Further refining these ideas, he developed sliding observers for steering angle estimation, eliminating the need for direct measurement — a practically valuable advance. His 1999 work on hybrid control for mobile robot action coordination (26 citations) added another dimension to his portfolio. Across his career, Stotsky has consistently bridged rigorous theoretical stability analysis with practical engineering solutions for autonomous systems.
