The invention provides an excavator rotation control method and system, a controller and electronic equipment, the method is applied to the controller, and the method comprises the steps that a handle angle value of a rotation handle is collected through a handle angle sensor installed on the rotation handle; the method comprises the following steps: acquiring a handle angle value of an excavator, determining a target rotation angle required by the excavator based on the handle angle value, determining a corresponding pressure value based on the target rotation angle, and controlling a proportional electromagnetic valve to provide pilot pressure corresponding to the pressure value to a pilot oil port connected with a rotary valve rod, so that the rotary valve rod moves leftwards or rightwards; and oil of an oil pump is controlled by the rotary valve rod to enter a rotary motor so as to drive the excavator to rotate at the target rotation angle required by rotation. Therefore, the angle required by rotation of the excavator is directly pre-judged through the angle of the rotation handle controlled by a driver so as to adapt to the requirements of different working conditions, so that the labor intensity of the driver is reduced, and the working efficiency is improved.
