This paper addresses the control problem of the Acrobot, a class of underactuated mechanical systems characterized by two links and a single actuator at the elbow. We propose a hybrid control strategy that achieves global stabilization. The method integrates an energy-based swing-up controller with a linear balancing controller. Unlike previous partial-feedback linearization methods, the proposed approach ensures that the region of attraction for the balancing controller is reached robustly. We demonstrate that by manipulating the total mechanical energy of the system, the Acrobot can be driven to its unstable equilibrium manifold, where a switching logic transfers control to a linear quadratic regulator (LQR) for asymptotic stability.

We ran controlled tests on three different machines (low-end laptop, mid-range desktop, high-end workstation). Here are the aggregated results: haja10 updated

Battery life on laptops improved by approximately 12% in standardized testing, thanks to the optimized sync engine that wakes the network radio less frequently. We ran controlled tests on three different machines

The synchronization engine has been rewritten in Rust, resulting in 40% faster delta syncs for large files (over 500 MB). Background syncs now consume 25% less CPU.

Fix: This is often caused by the re-indexing process, which runs once after the first launch. Let it complete (15–30 minutes). If it persists, disable Settings > Sync > Real-time file watcher and switch to manual or interval-based sync.

The proposed solution utilizes a hybrid control law consisting of two distinct phases.
