    Abstract: A method for servo locking control is provided. A servo enters a first lock state, and determines whether the current angular deflection values of the servo in a first preset period are all greater than a preset angular deflection value. When the current angular deflection values of the servo in the first preset period are all greater than the preset angular deflection value, the servo enters a second lock state, and determines whether the current angular changing values of the servo in a second preset period are all less than a preset angular changing value. When the current angular changing values of the servo in the second preset period are all less than the preset angular changing value, the servo enters the first lock state. A servo for performing the method for servo locking control is also provided.

    Abstract: The present disclosure discloses a command control in a multi-servo feedback control system. The command control includes: a servo acquiring preset delay time when a first action command is received from a main controller via serial data bus; the servo sending feedback information to the main controller after the preset delay time; wherein the preset delay time of the plurality of servos are different from each other, and the feedback information is configured to identify work status of the servo; receiving a second action command from the main controller; performing actions corresponding to the second action command and sending the feedback information to the main controller after the preset delay time if the second action command is valid. A servo and a multi-servo feedback control system for performing the command control are also provided.

    Abstract: A servo actuator ID setting method is performed by a servo actuator controlling system. The servo actuator controlling system includes a master controller and a plurality of servo actuators. One servo actuator is set to disconnect to a next servo actuator. A plurality of interfaces of the master controller are selected to turn on in sequence. The following steps are repeatedly performed to set servo actuator ID: broadcasting a signal to replace an original ID of each of the plurality of servo actuators with a target ID; the plurality of servo actuators in each branch connecting to the master controller; and replacing the original ID of each of the plurality servo actuator with the target ID.

A servo enters a first lock state, and determines whether the current angular deflection values of the servo in a first preset period are all greater than a preset angular deflection value. When the current angular deflection values of the servo in the first preset period are all greater than the preset angular deflection value, the servo enters a second lock state, and determines whether the current angular changing values of the servo in a second preset period are all less than a preset angular changing value. When the current angular changing values of the servo in the second preset period are all less than the preset angular changing value, the servo enters the first lock state.

    Abstract: An angle detection method includes collecting as original sample of an object angle, determining whether the original sample jumps, smoothing the original sample and outputting a smoothed original sample as a pre-processed sample. The method further includes determining whether a transition period of the original sample passes, updating the original sample during the transition period to the pre-processed sample, filtering the pre-processed sample, and outputting a non-interference detection value.
