Effectiveness of Sliding Mode Control for Robust Vision Stabilization under Plant-Binding Conditions
Overview
This research investigates the operational conditions for Boundary-layer Sliding Mode Control (SMC) in vision-based stabilization. The authors identify 'plant binding'—where disturbance velocity approaches actuator slew limits—as the critical condition where SMC outperforms simpler baselines like LPF and PID. Validated across handheld translation stabilization and angular re-framing against a slew-rate-limited PTZ plant, results show that outside binding conditions, SMC is statistically indistinguishable from LPF for translation but loses to PID in angular pointing offset; inside binding conditions, SMC significantly outperforms PID on the angular worst case. The study uses 12 1080p clips and simulated slew limits to demonstrate these findings.

“s in two independent vision domains: handheld translation stabilization (12 1080p clips; LPF, PID, SMC, L1) and angular re-framing against a virtual slew-rate-limited pan-tilt-zoom (PTZ) plant. Outside binding, leave-one-out cross-validation makes SMC and LPF on translation statistically indistinguishable, and PID beats SMC on the angular 99th-percentile pointing offset by 5.85 degrees (95% CI clear of zero); inside”
