The Lunqu Technology BallPlate system is a professional experimental platform designed for control theory research, robotics education, and algorithm development. Originally featured in the 2017 National College Student Electronic Design Contest, this system demonstrates dynamic stability and precision control through a ball balancing mechanism. Key Features: Ball-on-plate control system: A classic nonlinear control experiment where a ball is stabilized on a moving plate. PID control implementation: Supports proportional-integral-derivative algorithms for real-time balance. Educational and research use: Ideal for university labs, robotics courses, and demonstrations of control principles. STM32-based design: Provides high-performance computation and flexible programming options. Robust mechanical construction: Ensures repeatable experiments and long-term durability. Applications: Teaching control theory (PID, LQR, state-space methods) Robotics and automation training Algorithm verification for dynamic systems Demonstrations of nonlinear control principles
