摘要： A gimbal system includes a gimbal configured to support a load and including one or more motors configured to change an attitude of the load, one or more processors, and a memory coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the system to obtain a target control parameter of the one or more motors, and, in response to the gimbal switching from a power-on state to a powered-off state or a sleep state, control, according to the target control parameter, a torque of at least one of the one or more motors to decrease at a first speed within a first time period and to decrease at a second speed within a second time period after the first time period. The second speed is lower than the first speed.

摘要： An abnormality diagnosis system performs an abnormality diagnosis of a plurality of motor systems that include a motor for moving a moving body. The abnormality diagnosis system identifies a comparison target system that is the motor system, among the motor systems, that is a comparison target in relation to a diagnosis target system that is the motor system to be a target of the abnormality diagnosis. The abnormality diagnosis system acquires a state-related value that is a value related to an operation state of the motor from each of the diagnosis target system and the comparison target system. The abnormality diagnosis system performs a comparison of the state-related value that is acquired from the diagnosis target system and the state-related value that is acquired from the comparison target system, and diagnoses a presence or absence of an abnormality in the diagnosis target system using a result of the comparison.

摘要： A torque control system is configured to automatically determine the fully open position and fully closed position of the valve without the need of manual operation of the valve. In addition, a control unit of the torque control system can obtain a control parameter based on a driving device operation signal detected by a detection unit, and output a control command to a driving unit to change an operation parameter of the driving device, so that the torque applying by the driving device on the valve can be adjusted, therefore the torque control system of the present application can accurately output the operating torque required by the valve, so that there is no circumstances that the operating torque is too large to damage the valve or the operating torque is too small to be unable to drive the valve.

摘要： Monitoring and control of power or drive couplings in mechanical drive systems is performed using sensors at an interface of the coupling and an overload disengagement component at the coupling. A local sensor and actuation module having a wireless communication port receives signals from the sensors and uses the signals to monitoring a load on the drive coupling. An overload disengagement circuit responsive to the monitored load and provides a disconnect signal responsive to a sensed overload condition, and communicates with the local sensor and actuation module using an Internet of Things (IoT) link, using a blockchain enablement protocol. The local sensor and actuation module provide an override capability in the event of a communication failure of the IoT link.

摘要： A gimbal control method includes configuring, while a gimbal is in a power-on state, turning-off motor control parameters according to a mass of a camera device carried by the gimbal. The gimbal includes an electric motor. The turning-off motor control parameters are configured to control the electric motor when the gimbal is powered off or enters a sleep state. The method further includes, in response to the gimbal being powered off or entering the sleep state, controlling a torque of the electric motor to decrease gradually from a starting moment at which the gimbal is powered off or enters the sleep state according to the turning-off motor control parameters.
