To shorten the design period of control system of a satellite attitude control flywheel,and to verify the feasibility and effectiveness of design schemes,a control model based on a mathematics model for flywheels was established combined with acceleration techniques,reversal connection braking control and commutation control for the control system of flywheels. By taking the speed instruction in a speed control mode for an example,the speed responses,currents,terminal voltages and torques were analyzed by the variable voltage speed control method and the variable voltage speed control combined with reversal connection braking method.The results indicate that the latter has better performance than that of the variable voltage speed control method at a speed instruction of 0.025 Hz.
