Abstract
En 中文
• Proposal of a low-complexity backlash mitigation strategy based on input-shaped Terminal Iterative Learning Control (TILC) for EV powertrains. • Elimination of explicit backlash state estimation by learning the switching time of a slope-limited bang-bang torque. profile • Development of a model-based compensation scheme to handle iteration-varying disturbances and sampling-time. effects • Experimental validation on a drivetrain testbench demonstrating improved backlash reduction and drivability performance.
