Moment equilibrium controller in redundant actuation system

Abstract

The invention relates to a moment equilibrium controller in redundant actuation system, wherein a power supply management module supplies power to a communication protocol module and a control module via a printed circuit, the control module and the communication protocol module as well as the communication protocol module and a high-speed communication physical interface module are both interconnected via the printed circuit, and the control module realizes external communication via the communication protocol module and the high-speed communication physical interface module; the working frequency of the control module is not less than 10MHz, the communication protocol module needs to be matched with a high-speed communication physical interface which is reserved by a servo driver of the redundant system, and the maximal baud rate of the high-speed communication physical interface is not less than 100kHz. The control module and the communication protocol module adopt DSP chip TMS320F28335 from TI Corp. or SOPC single chip machine C8051F040 from Cygnal Corp. The high-speed optical coupling isolation chip adopts 6N137 and the bus physical drive chip adopts TJA1050T.

Description

technical field [0001] The invention belongs to a load moment balance controller of each motor in a redundant drive system. The device is used in the fields of special radar redundant drive control system, other redundant drive control systems and dual motor drive systems. Background technique [0002] In some occasions with special needs, such as air traffic control radar servo system, etc., the reliability of the drive system is very high. In order to reduce the probability of system failure, a redundant drive system is generally used to meet its high reliability requirements. [0003] In the redundant drive system, multiple sets of drive systems are used for drive according to the drive power. The common one is dual-motor drive. The redundant dual-motor drive servo system includes two sets of drive systems and two sets of control systems. The specific implementation plan Please refer to the document "Application of Redundancy Design in Air Traffic Control Radar Antenna D...
