The invention provides an aircraft turning system combining a front wheel and a main wheel. The aircraft turning system comprises a control template, an on-off input unit, an analog input unit and an analog output unit, the control template is used for executing a cooperative control strategy; a turning radius is calculated according to a front wheel turning instruction sensing signal and a real-time sliding speed parameter; calculating an inner main wheel turning angle and an outer main wheel turning angle by using the turning radius and structural parameters among the front wheel, the inner main wheel and the outer main wheel of the airplane, and outputting an inner main wheel turning servo signal and an outer main wheel turning servo signal; the error between the inner main wheel angle/position feedback sensing signal and the inner main wheel rotation angle is calculated according to the inner main wheel angle/position feedback sensing signal, the front wheel turning compensation angle is calculated, and a front wheel turning servo signal is output. According to the asymmetric control strategy for the inner and outer side wheels, asymmetric cooperative control over the main wheels on the two sides can be achieved, meanwhile, steering angle feedback control over the front wheels is conducted in real time, and synchronous control over aircraft steering between the front wheels and the main wheels is achieved.

    本发明提供了一种结合前轮与主轮的飞机转弯系统,包括:控制模板、开关量输入单元、模拟量输入单元和模拟量输出单元;控制模板用于执行协同控制策略:根据前轮转弯指令传感信号和实时滑行速度参数计算得到转弯半径;利用转弯半径以及飞机前轮、内主轮和外主轮之间的结构参数计算内主轮转角和外主轮转角,并输出内主轮转弯伺服信号和外主轮转弯伺服信号;根据内主轮角度/位置反馈传感信号计算其与内主轮转角的误差计算前轮转弯补偿角,并输出前轮转弯伺服信号。本发明提出了一种内外侧轮非对称控制策略,能够实现两侧主轮非对称协同控制的同时,对前轮实时进行转向角度反馈控制,实现前、主轮之间飞机转向的同步控制。
