In order to Shorten design period of control system of flywheels for satellite attitude control

and verify feasibility and effectiveness of design scheme

a model for of flywheels is established on the basis of analysis of motor’s mathematics model Combined with methods used in control system of flywheels such as acceleration techniques

reversal connection braking method

commutation control and etc. Based on speed instruction in speed control mode

responses of speed

current

terminal voltage and torque are presented under Variable Voltage Speed Control method and Variable Voltage Speed Control combined with reversal connection braking method. Finally

results indicate that under 0.025Hz speed instruction Variable Voltage Speed Control combined with reversal connection braking method have a better performance than Variable Voltage Speed Control method. Key words: Satellite attitude control flywheel; System design; Reversal connection braking;
