The software which controls this process is able to measure the success of previous changes to the rotorAngle and use that information to fine-tune future attempts to dampen wave-induced movement.
Last, MATLAB6.1 as simulation tool is used to make research for the whole SRD system and operating characteristics and rotor position Angle estimation.
Now commonly used servo motor is ac servo motor, the axial end in motor with photoelectric encoder, by examining the rotorAngle to frequency conversion control.
