摘要： A non-drive dynamic stabilizer includes a damper and an actuator. The dynamic stabilizer provides multiple states of support to a solar tracker structure. These states may include 1) flexible movement and/or damping during normal operation (i.e. tracking) and/or 2) rigid or locked, whereby the dynamic stabilizer acts as a restraint. The dynamic stabilizer is actuated by a control system according to the real-time demands on the structure. Sensors to provide input to the control system may include wind speed sensors, wind direction sensors, snow sensors, vibration sensors and/or displacement sensors.
