摘　　要：目前飞机起落架的前轮转弯通常使用液压系统进行驱动,液压驱动前轮转弯是现在大、中型飞机的主流方式。但液压系统具有管路长、负荷大、易漏油等缺陷。多电飞机中以电机作为飞机前轮转弯的动力源能够有效地避免液压系统的缺陷。针对多电飞机前轮转弯需求,以转弯角度为被控对象,该文设计了以DSP为核心的前轮转弯控制系统,能够实现多电飞机前轮转弯角度的控制。At present,the front wheel turning of aircraft landing gear is usually driven by hydraulic system.Hydraulic driving for front wheel turning is the mainstream way of large and medium aircraft.However,hydraulic system has many defects,such as long pipeline,large load and oil leakage.In more electric aircraft,taking motor as the power source of aircraft front wheel turning system can avoid the defects of hydraulic system.According to the requirements of front wheel turning of more electric aircraft,taking the turning angle as the control object,a front wheel turning control system based on DSP is designed,which can realize the control of front wheel turning angle of more electric aircraft.
