For the underwater multilifting platform transmited by wire rope remotely, positioning accuracy is an important condition to guarantee the performance effect, so it needs to ensure the height of zero position consistently, and to pledge high positioning accuracy during operation. It is difficult to guarantee the zero position of each platform determined by the mechanical limit switch in the same plane and it needs a heavy workload， and the elastic elongation of wire rope is different caused by the resistance change in system, thus the position control accuracy was affected. According to these problems, force analysis of the lifting platform was performed, and a position control method based on compensation was designed by measuring the zero error and turning error, then zero compensation and turning compensation were actualized to improve positioning accuracy. Finally, the method was verified in the actual platform, and it proves that the compensation method is easy to implement and can effectively improve the position control accuracy.
