The given work is devoted <This paper focuses on the electric drive system of a crane with a rated load capacity of 500 kg, using the following basic parameters: gravitational acceleration 9.8 m/s², worm reducer efficiency 0.7, drum diameter 0.65 m, reducer transmission ratio 30, and motor pole number 2. The study aims to analyze the kinematic and dynamic characteristics of the crane mechanism, determine the appropriate motor specifications and perform parameter calculations, establish mathematical models for both scalar V/f control and vector control of the induction motor, and develop a load oscillation compensation algorithm to mitigate load deflection during crane operation. Through theoretical calculations, mathematical modeling, and simulation comparisons, the dynamic performance, starting characteristics, and speed regulation accuracy of scalar V/f control versus vector control were analyzed under various operating conditions including acceleration, rated load operation, and braking. Simulation results demonstrate that compared to scalar control, vector control exhibits superior low-speed torque output capability, faster dynamic response speed, and smaller rotational speed fluctuations. The designed load oscillation compensation algorithm effectively reduces crane load swing angles and residual oscillations, thereby enhancing equipment operational safety and work efficiency.>.
