应理解,上述对于无人飞行系统各组成部分的命名仅是出于标识的目的,并不应理解为对本发明的实施例的限制。
图2为本发明一实施例提供的无人机的控制方法的流程图,如图2所示,本实施例的方法可以包括:
S201、获取翻滚指令,所述翻滚指令用于控制所述无人机朝第一翻滚方向翻滚。
S202、根据所述翻滚指令,在所述无人机朝上的飞行速度大于或等于预设速度时,控制所述无人机朝第一翻滚方向加速翻滚。
S203、控制所述无人机朝所述第一翻滚方向减速翻滚。
S204、在所述无人机朝第一翻滚方向翻滚一周时,控制所述无人机停止翻滚。
本实施例中,获取翻滚指令,所述翻滚指令用于控制所述无人机朝第一翻滚方向翻滚;然后根据该翻滚指令,在无人机朝上的飞行速度大于或等于预设速度时,控制无人机朝该第一翻滚方向加速翻滚,以驱动无人机快速翻滚;然后再控制无人机朝所述第一翻滚方向减速翻滚,在无人机朝第一翻滚方向翻滚一周时,表示无人机已翻滚360度,表示翻滚过程结果,然后控制无人机停止翻滚。在一些实施例中,在无人机朝第一翻滚方向翻滚一周时,控制无人机朝朝所述第一翻滚方向的角速度减速为0,以控制所述无人机停止翻滚。需要说明的是,上述S201-S204可以是均由无人机执行,其中,无 人机获取翻滚指令可以为:无人机生成翻滚指令,或者,无人机从控制设备接收翻滚指令。或者,上述S201由控制设备执行,上述S202-S204由于无人机执行。
由于本实施例是在无人机朝上的飞行速度大于或等于预设速度时,控制无人机加速翻滚,该预设速度例如是大于0的值,因此,在无人机的初始翻滚阶段,无人机在高度方向上仍然向上飞行一段距离。在翻滚过程中,由于重力的作用,无人机会这样在无人机翻转一定角度之后,无人机的螺旋桨朝下,无人机产生的动力相当于会驱动无人机朝下飞行,同时无人机的重力也会驱动无人机朝下飞行,这样无人机在高度方向上会向下飞行一段距离,向上飞行的距离会抵消向下飞行的距离,从而使得无人机在翻滚一周后,在高度方向的变化不大,避免掉高现象。
在一些实施例中,本实施例在控制所述无人机朝所述第一翻滚方向加速翻滚之前,还控制所述无人机的动力输出以控制所述无人机向上加速飞行,以使无人机向上的飞行速度大于或等于所述预设速度。所述翻滚指令可以是无人机在悬停状态获取到的,也可以是无人机在飞行状态下获取到的,因此,在获取到翻滚指令后,无人机的当前飞行参数会存在差异,所以无人机向上的飞行速度也会不同,可能小于预设速度,也可能大于或等于预设速度。若无人机向上的飞行速度大于或等于预设速度时,则无人机直接朝第一翻滚方向加速翻滚;若无人机向上的飞行速度小于预设速度时,则控制无人机的动力输出以给无人机输出向上的加速度,从而控制无人机向上加速飞行,直至无人机向上的飞行速度加速至大于或等于预设速度时,控制无人机朝第一翻滚方向加速翻滚。本实施例中,通过控制无人机向上加速,使得无人机在开始翻滚时具有较大的向上速度,以避免翻滚过程中的掉高现象。
在一些实施例中,所述预设速度与所述无人机的自重以及无人机动力系统的效率正相关。本实施例中,在翻滚的一段时间内,无人机输出的动力虽然使得螺旋桨的拉力在垂直方向上的投影是朝上的,但不足以抵消重力;或者,无人机输出的动力使得螺旋桨的拉力在垂直方向上的投影是朝下的;此时重力与螺旋桨的拉力在垂直方向上的投影分量会共同作用,使得无人机产生向下的大于0的加速度,无人机的速度会急剧向下增加,影响到无人机向下的飞行距离,因此可以认为无人机向下飞行的飞行距离受到无人机的自重 以及无人机动力系统的效率的影响。而且本实施例是在无人机向上的飞行速度大于或等于预设速度时开始朝第一翻滚方向加速翻滚,因此,预设速度可以影响无人机向上的飞行距离。为了避免掉高现象,该无人机向上的飞行距离尽可能与向下的飞行距离相同,因此,预设速度也受到无人机的自重以及无人机动力系统的效率的影响。
在一些实施例中,控制无人机朝第一翻滚方向加速翻滚的一种可能的实现方式包括:控制所述无人机的动力输出,以使所述无人机的角加速度达到第一角加速度并保持所述第一角加速度朝所述第一翻滚方向以均角加速度加速翻滚。本实施例中,在控制无人机朝第一翻滚方向加速翻滚时是以均角加速度加速翻滚,其中,该均角加速度为第一角加速度,具体地,控制无人机的动力输出,以使无人机的角加速度为第一角加速度,在无人机的角加速度为第一角加速度时,控制无人机朝第一翻滚方向以恒定的第一角加速度加速翻滚,在此翻滚过程中,无人机的角速度增加。
在一些实施例中,控制无人机朝第一翻滚方向减速翻滚的一种可能的实现方式包括:控制所述无人机的动力输出,以使所述无人机的角加速度达到第二角加速度并保持所述第二角加速度朝所述第一翻滚方向以均角加速度减速翻滚。本实施例中,在控制无人机朝第一翻滚方向减速翻滚时是以均角加速度减速翻滚,其中,该均角加速度为第二角加速度,具体地,控制无人机的动力输出,以使无人机的角加速度为第二角加速度,在无人机的角加速度为第二角加速度时,控制无人机朝第一翻滚方向以恒定的第二角加速度减速翻滚,在此翻滚过程中,无人机的角速度减少。
在一些实施例中,所述第一角加速度与第二角加速度大小相同,方向相反。由于第一角加速度与第二角加速度方向相反,因此,在第一角加速度时无人机为加速翻滚,相应地,在第二角加速度时,无人机为减速翻滚。
在一些实施例中,所述控制所述无人机朝所述第一翻滚方向减速翻滚的一种可能的实现方式可以包括:在所述无人机翻滚过预定路径长度时,控制所述无人机朝所述第一翻滚方向减速翻滚。在无人机朝第一翻滚方向开始翻滚时开始累计无人机翻滚的路径长度,在无人机翻滚的路径长度为预定路径长度时,控制无人机朝第一翻滚方向减速翻滚。在一些实施例中,预定路径长度与预定时长有关,即表示无人机翻滚过预定路径长度时需要翻滚过预定 时长,因此,本实施例还可以在无人机朝第一翻滚方向开始翻滚时开始计时,在无人机翻滚的时长为预定时长时,控制无人机朝第一翻滚方向减速翻滚。
在一些实施例中,在控制无人机朝所述第一翻滚方向减速翻滚之前,还在所述无人机的角速度加速至预设角速度时,控制所述无人机的动力输出以使所述无人机以所述预设角速度匀速翻滚。本实施例中,控制无人机朝第一翻滚方向加速翻滚,无人机的角速度增加,在无人机的角速度增加至预设角度速度时,无人机的角速度不再增加,而是以预设角速度匀速翻滚。其中,该预设角速度可以是无人机的最大角速度。
在一些实施例中,在所述无人机翻滚的过程中所述无人机输出的动力与所述无人机的姿态角以及所述翻转指令的控制有关。其中,若无人机的姿态角小于某一阈值(例如俯仰角(θ)小于45度,横滚角(Φ)小于45°),则无人机输出的动力最大,例如100%,使得无人机快速上升,以获取较大的上升速度。若无人机的姿态角大于某一阈值,则无人机输出的动力最小,以尽量减少在翻转过程中,由于拉力方向朝下所引起的掉高现象。
在一些实施例中,翻滚指令可以是无人飞行器的控制设备生成的。
在一些实施例中,若控制设备是控制终端,例如智能手机或平板电脑等,则可以检测到对交互界面的第一操作,然后根据该第一操作,生成所述翻滚指令。在一些实施例中,所述第一操作为滑动操作;本实施例可以根据滑动操作,生成所述翻滚指令,其中,所述第一翻滚方向与滑动操作的滑动方向有关;或者,所述第一翻滚方向与所述滑动操作的起点至终点的方向有关。因此,本实施例的无人机的翻滚方向可以根据滑动操作而改变,即可实现无人机朝任意方向翻滚。
在一些实施例中,若控制设备是控制终端,则可以根据用户向所述无人机的控制终端输入的俯仰角和横滚角,生成所述翻滚指令;其中,所述第一翻滚方向与所述俯仰角和所述横滚角有关。其中,可以根据俯仰角和横滚角生成一个向量,将该向量的方向作为第一翻滚方向。
在一些实施例中,若控制设备可以是遥控装置,则可以获取遥控装置的摇杆的杆量;根据所述杆量,生成所述翻滚指令。在一些实施例中,杆量包括摇杆的偏移方向和在偏移方向的偏移量,所述第一翻滚方向与根据所述摇杆的偏移方向有关,所述无人机的翻滚速度与所述摇杆的偏移量有关。
在一些实施例中,获取翻滚指令之后,控制无人机的翻滚过程可以包括五个阶段,如图3所示。
第1阶段为加速上升阶段。在这一阶段中主要是提供一个向上的较大的初始速度,以防止无人机在翻滚过程中,无人机掉高严重,造成飞行事故。在这一阶段,控制无人机的动力输出以控制所述无人机向上加速飞行,直至无人机向上的飞行速度大于或等于预设速度时,进行第2阶段。所述预设速度与所述无人机的自重以及无人机动力系统的效率正相关。其中,所述预设速度与所述无人机的自重以及无人机动力系统的效率正相关。
第2阶段为加速翻滚阶段。在无人机以向上的飞行速度大于或等于预设速度时,控制无人机的动力输出以使所述无人机的角加速度达到第一角加速度,然后保持该第一角加速度朝第一翻滚方向以均角加速度加速翻滚,直至无人机的角加速度加速至预设角加速度时,进行第3阶段。该预设角加速度为无人机在翻滚过程中的最大角速度。
第3阶段为匀速翻滚阶段。在无人机的角加速度加速至预设角加速度时,控制无人机的动力输出以使所述无人机的角加速度为0,此时不再对无人机的角速度进行加速,无人机的角速度保持在预设角速度的大小进行匀速翻滚,在无人机共翻滚过预定路径长度或者预定时长时,进行第4阶段。
第4阶段为减速翻滚阶段。在无人机共翻滚过预定路径长度或者预定时长时,控制无人机的动力输出以以使所述无人机的角加速度达到第二角加速度,然后保持该第二角加速度朝第一翻滚方向以均角加速度减速翻滚,直至无人机的角加速度减速至0时,进行第5阶段。其中,所述第一角加速度与第二角加速度大小相同,方向相反。
第5阶段为悬停阶段。在无人机的角加速减速至0时,控制无人机的动力输出以使所述无人机的角加速度为0,此时不再对无人机的角速度进行减速,无人机的角速度为0,无人机不再翻滚,保持悬停状态。其中,无人机处于第5阶段时的高度认为是与无人机在第1阶段开始时的高度相同。
其中,图4为本发明一实施例提供的翻滚时间与角速度的示意图,如图4所示,第2阶段的翻滚时长为t1,第3阶段的翻滚时长为t2-t1,第4阶段的翻滚时长为t3-t2。其中,无人机的翻滚总时长为t3,t3的大小根据实际应用场景而设定,与用户所需无人机的翻滚快慢有关,若用户期望无人机翻滚 越快,则t3越小,若用户期望无人机翻滚越慢,则t3越大。其中,根据无人机的硬件支持可以确定出无人机的最大角速度,将该最大角速度设定为预设角速度,在确定出预设角速度后,可以确定出上述的第一角加速度和第二角加速度,还可以确定出t1和t2。在一些实施例中,若无人机的硬件支持足够好(例如角速度传感器的量程足够大),则无需匀速翻滚阶段,即无需图4所示的t1~t2阶段,因此,无人机在翻滚阶段是先加速翻滚再减速翻滚,如图5所示。
