Self-powered active control system design based on energy analysis

A self-powered active control system was designed. First, a kind of drive mode of motor actuator for self-powered active control was given, so that the actuator can work in three modes and switch functions. Second, the relationship between proportion of working hours and energy balance was analyzed, and the basic conditions to achieve energy balance were given, then the conditions of the system energy balance were obtained. Finally, the feasibility of the method was verified by a designed self-powered active control system. The simulation indicates that the active control system can effectively reduce the interference of vibrational excitation, and the energy balance of the system is achieved, which means that the control system does not require an external energy supply.
