如图1所示，恒功率控制装置至少包括：电压采集结构110、与所述电压采集结构相连的电流采集结构120、以及与电流采集模块和电压采集结构均相连的控制结构130。
电压采集结构110用于采集电子器件的供电电压。
示意性地，电压采集结构110连接至电子器件的供电电压端，以采集电子器件的供电电压。电子器件的供电电压可以为供电电压，或者为处理后的供电电压，本实施例不对电子器件的供电电压的类型作限定。
比如：电压采集结构包括采样电阻，采样电阻的电压值为供电电压。
电流采集结构120用于将供电电压反应初的电压进行深度滤波，从而得到直流的电压，该电压对应的电流与供电电压对应的供电电流满足一定关系。
具体地，电流采集结构120包括滤波单元121和采样单元122。相应地，电流采集结构120用于通过滤波单元121进行电流过滤，并经过采样单元122进行电流采样后，得到当前采样电流。
在一个示例中，电压采集结构110通过滤波单元121与采样单元122相连。此时，电压采集结构110采集到的供电电压先经过滤波单元121过滤，得到过滤后的电压；然后，采样单元122对过滤后的电压进行电流采样，得到当前采样电流。
在另一个示例中，电压采集结构110通过采样单元122与滤波单元121相连。此时，电压采集结构110采集到的供电电压先经过采样单元122进行电流采样，得到采样电流；然后，滤波单元121对采样电流进行滤波，得到当前采样电流。
示意性地，滤波单元121包括串联的电阻和电容。采样单元122包括模数转换器(Analog-to-Digital Converter，ADC)。
可选地，电压采集结构110采集的供电电压经过运放电路放大后输入电流采集结构120，这样，可以通过反馈网络调整供电电压。
控制结构130用于获取电流对应关系；在电流对应关系中确定当前采样电流对应的当前供电电流；基于目标功率和供电电压确定目标供电电
流；以及，将当前供电电流调节至目标供电电流。
根据上述结构可知，电流采集结构120将供电电压反应初的电压进行深度滤波后，得到当前采样电流与当前供电电压对应的当前供电电流存在一定关系，这种一定关系即为电流对应关系。换言之，电流对应关系用于表示不同采样电流与每个采样电流对应的供电电流之间的对应关系。电流对应关系预存在恒功率控制装置中。这样，基于电流对应关系可以确定出当前供电电流，而根据目标功率和当前供电电压可以确定出电子器件的目标供电电流，将当前供电电流调整至目标供电电流即可实现电子器件的恒功率输出。
示意性地，电流对应关系为线性对应关系。这样，可以保证每个当前采样电流可以确定出唯一对应的当前供电电流。
其中，目标功率为期望电子器件所能达到的恒定功率。可选地，目标功率预存在恒功率控制装置中。在电子器件包括至少两种工作档位的情况下，不同工作档位对应不同的目标功率，本实施例不对目标功率的设置方式作限定。
下面对该电子器件的恒功率控制方法进行介绍。下述实施例以该方法用于图1所示的恒功率控制装置中为例进行说明，在实际实现时，也可以用于与该恒功率控制装置通信相连的其它设备中，比如手机、计算机、可穿戴式设备、或者平板电脑等设备中，本实施例不对该恒功率控制方法的应用场景作限定。
图2是本申请一个实施例提供的电子器件的恒功率控制方法的流程图，该方法至少包括以下几个步骤：
步骤201，获取电流对应关系，电流对应关系用于表示不同采样电流与每个采样电流对应的供电电流之间的对应关系。
可选地，电流对应关系预存在恒功率控制装置中，或者由其它设备发送至恒功率控制装置。
示意性地，电流对应关系的获取方式包括：获取电子器件的当前供
电电流和该当前供电电流对应的当前采样电流；基于当前供电电流和当前采样电流构成的多组样本数据，生成电流对应关系。
具体地，基于多组样本数据生成电流对应关系的方式可以为：曲线拟合方式、或者使用预设线性模型生成，本实施例不对电流对应关系的生成方式作限定。
可选地，电流对应关系为线性对应关系，即将当前采样电流乘以某个系数再加上一个常数即可得到对应的当前供电电流。
步骤202，在电流对应关系中确定当前采样电流对应的当前供电电流。
其中，当前采样电流是电流采集结构采集到的，电流采集结构包括滤波单元和采样单元；电流采集结构用于通过滤波单元进行电流过滤，并经过采样单元进行电流采样后，得到当前采样电流。
步骤203，基于目标功率和供电电压确定目标供电电流。
其中，供电电压由电压采集结构采集，电压采集结构用于采集电子器件的供电电压。
具体地，目标功率除以供电电压即为目标供电电流。
可选地，步骤203可以在步骤201和202之后执行；或者，可以在步骤201和202之前执行；或者，还可以与步骤201和202同时执行，本实施例不对步骤203的执行时机作限定。
步骤204，将当前供电电流调节至目标供电电流。
示意性地，将当前供电电流调节至目标供电电流，包括：确定当前供电电流与目标供电电流之间的误差值；基于该误差值使用比例、积分和微分(Proportion Integral Differential，PID)控制算法，将当前供电电流调节至目标供电电流。
可选地，恒功率控制装置每隔预设时间阈值调节一次供电电流。此时，将当前供电电流调节至目标供电电流，包括：确定当前时间与上次电流调节结束时间之间的时间间隔是否大于预设时间阈值；在时间间隔大于或等于预设时间阈值的情况下，将当前供电电流调节至目标供电电
流；在时间间隔小于预设时间阈值的情况下，触发执行在电流对应关系中确定当前采样电流对应的当前供电电流；基于目标功率和供电电压确定目标供电电流；确定当前时间与上次电流调节结束时间之间的时间间隔是否大于预设时间阈值的步骤。
综上所述，本实施例提供的电子器件的恒功率控制方法，通过获取电流对应关系，电流对应关系用于表示不同采样电流与每个采样电流对应的供电电流之间的对应关系；在电流对应关系中确定当前采样电流对应的当前供电电流；基于目标功率和供电电压确定目标供电电流；将当前供电电流调节至目标供电电流；可以解决无法实现对电子器件的恒功率控制的问题；由于可以基于电流对应关系可以确定出当前供电电流，而根据目标功率和当前供电电压可以确定出电子器件的目标供电电流，将当前供电电流调整至目标供电电流即可实现电子器件的恒功率输出。
另外，传统的电机的恒功率控制方式中，通过对电机的DQ轴的电压进行计算来调节功率。但是，在电机负载变化时，会发生功率偏移，依然无法做到真正的恒功率。基于此，本实施例中，通过对电流采集结构采集的供电电压进行深度滤波得到当前采样电流，该当前采样电流不随电机的负载的影响，因此，可以保证持续不同负载状态下的功率值，达到不同负载状态下的恒功率控制。
为了更清楚地理解本申请提供的电子器件的恒功率控制方法，下面对该方法举一个实例进行说明，参考图3，该方法至少包括以下几个步骤：
步骤31，基于目标功率和供电电压确定目标供电电流；
步骤32，在电流对应关系中确定当前采样电流对应的当前供电电流；
步骤33，确定是否到达电流调节时间；若是，则执行步骤34；若否，则再次执行步骤31；
步骤34，确定目标供电电流与当前供电电流之间的误差值；
步骤35，将误差值使用PID算法调节得到调节占空比；
步骤36，按照调节占空比调节当前供电电流，再次执行步骤31，直
至电子器件停止工作。
根据上述过程可知，当前采样电流不随电机的负载的影响，可以保证持续不同负载状态下的功率值，达到不同负载状态下的恒功率控制。
