Design of cross redundant servo device control system for space nuclear power reactor control drum and control rod drive mechanism

The control drum and control rod of space nuclear power reactor requires highly reliable drive control.The device that implements this drive control is defined as control drum and control rod drive mechanism drive control device,refers to the nuclear reactor control computer command into the drive mechanism of the drive signal,and through the collection of the state of the drive mechanism,multiple sets of control drum and control rod precise control of the control system design of a cross redundant servo drive control device with dual-redundant controller to multiple dual-redundant mechanismsis achidued based on aerospace flight products.The controller is composed of two sets of backup logic control units,motor cross-redundancy switching unit,switching unit of rotation measurement signal,analog adjustment and switching unit,electromagnetic driving control unit and nine sets of motor driving unit,and communicates with the stack control computer through 1553 B.Through a prototype of the drive controller the equipment has good environmental adaptability to space,the system interface also meets the requirements of space-related norms.
