Abstract: To address the issues of low efficiency, poor accuracy, and safety hazards associated with manual connections of high-voltage gas-insulated switchgear (GIS), this paper introduces a specialized intelligent gripper system and control algorithm. In terms of hardware, an innovative three-finger radial synchronous gripper is developed, featuring a carbon fiber composite finger tip and a parallel disc spring-rail dual-level adaptive mechanism, which compensates for ±3.5mm pose deviation. The perception system integrates six-axis force sensors and laser rangefinders, with dynamic gravity compensation and Kalman filtering, achieving a force resolution of 0.1N and a pose estimation error less than or equal to 0.03 mm. At the algorithm level, a hierarchical control architecture is proposed. Gain-scheduled adaptive gripping control enhances robustness through gain scheduling strategies. Directionally decoupled force-position hybrid compliant control constructs a stiffness matrix to achieve coordinated tangential low stiffness and normal adaptive stiffness. The force-position deviation mapping algorithm achieves angle error convergence at the 0.04° level. After 50 full-process tests on GIS simulation pieces, the system has a 98% connection success rate, 93.2% seal compression uniformity, a 38.7% reduction in contact force peak, and a single operation time of 4.1 minutes, significantly enhancing assembly automation.
