A handheld 3-axis gimbal stabilizer can eliminate vibrations enabling smooth smartphone shooting through the three-gyroscope chip with self-adaptive 3-Axis mixing which applies a correction based on proportional, integral, and derivative terms (PID)* an algorithm that controls the three motors to achieve automatic stability and balance in the shooting process.
In practical terms, [such a controller] automatically applies accurate and responsive correction to a control function. An everyday example is the cruise control on a vehicle; where external influences such as gradients (hills) would cause speed changes, and the driver has the ability to alter the desired set speed. The PID algorithm restores the actual speed to the desired speed in the optimal way, without delay or overshoot, by controlling the power output of the vehicle's engine.
