Comprehensive Analysis of Active Vibration Control Technology: From Breakthrough Principles to Precise and Stable Intelligent Solutions
What is Active Vibration Control Technology?
Traditional passive vibration isolation exhibits significant performance degradation at low frequencies (<10Hz). Active vibration control technology employs a closed-loop “sensing-decision-execution” system to generate counter-vibrations in real time, neutralizing disturbances. This makes it a core enabler for fields like lithography machines and quantum experiments.
Active Vibration Control Technology: Comprehensive Breakthroughs from “Nano-Sensing” to “Precision Force Control”
Precise sensing forms the bedrock of active vibration control. The system employs high-precision accelerometers, laser vibrometers, and other instruments to capture vibration amplitude, frequency, and phase in real-time at microsecond sampling rates. This achieves “nano-level signal capture,” providing millimeter-accurate data support for subsequent control operations.
The decision layer, acting as the “intelligent algorithm hub,” rapidly calculates counteracting forces based on sensing data. While classic PID control meets basic requirements, modern complex scenarios increasingly rely on adaptive algorithms (e.g., LMS, RLS) and machine learning models to dynamically optimize control parameters, achieving millisecond-level response.
Finally, the execution layer employs “muscle-grade” actuators—piezoelectric ceramics (PZT) delivering nanosecond-speed nanometer-level displacement, while voice coil motors (VCM) cover low-frequency, high-amplitude scenarios. Their synergy achieves “precise force feedback realization,” forming a complete closed-loop from signal capture to vibration cancellation.
