Description

technical field [0001] The invention belongs to the technical field of electromechanical control, and more particularly, relates to a timing control circuit and method of a servo system. Background technique [0002] With the wide application of servo systems in high-tech weapons and equipment such as optoelectronics, radar, and fire control, the model weapon system has the advantages of high precision, high dynamic performance, high light weight ratio, high integration, low power consumption, low power consumption and low power consumption. Costs and other aspects put forward higher requirements. With the continuous improvement of the power of the servo system, especially in the supporting servo test, the higher the requirements for the power-off sequence function are. [0003] At present, most of the servo systems of domestic weapon models use power reverse control technology, but most of this scheme requires the control and drive power-off sequence requirements, which of...

Problems solved by technology

[0003] At present, most of the servo systems of domestic weapon models adopt power reverse control technology, but most of these solutions have control and drive distribution and power-off timing requirements, and often cause damage to product components due to power-off errors. , the traditional solution is mainly to increase the power distribution control circuit in the power supply part, but with the continuous improvement of servo power and power-to-quality ratio, it is difficult for this circuit design to meet the current design requirements for light weight, power consumption and cost. It is an inherent defect in the design of the servo system control drive circuit
