Abstract: A controller for controlling a motor comprises a processor and a memory having instructions stored thereon that, when executed by the processor, cause the controller to collect a feedback signal indicative of the current state of an operation of the motor and determine current constraints on parameters of the operation of the motor using model of dynamics of the motor connecting the current state of the motor with the current constraints on the operation. The processor is further configured to determine a control trajectory of the operation of the motor based on the current constraints on parameters of the operation of the motor using a parametrized estimation agnostic to the dynamics of the motor and control the operation of the motor according to the control trajectory.

Abstract: An engineering system comprises a memory having instructions stored thereon and at least one processor configured to execute the instructions to cause the system to collect a plurality of tasks for a manipulator actuated by a motor. Structural parameters of the motor, a plurality of reference trajectories of the motor for actuating the manipulator to perform the plurality of tasks, and parameters of a feedback control policy for the manipulator are jointly determined to increase overlap between a probability distribution of values of operational data of the motor operating according to different real trajectories from a plurality of real trajectories and an efficiency map of the motor defined in a domain of the operational data of the motor. The structural parameters of the motor, the plurality of reference trajectories, and the feedback control policy are output for performing the plurality of tasks.

Abstract: A dust collecting pile includes: a pile base provided with a dust inlet in a top surface of the pile base; a pile body disposed on the pile base, and including a fan cavity and a dust bin; a fan disposed in the fan cavity and configured to form a negative pressure in the dust bin; and a bag support disposed in the dust bin, where a dust outlet port is provided in a sidewall of the bag support, and the dust outlet port is in connection with the dust inlet through a dust channel, where the bag support further includes a sliding baffle slidably provided on the sidewall and configured to be switchable between a first position and a second position, and the sliding baffle is configured to cover the dust outlet port in response to being in the first position and expose the dust outlet port in response to being in the second position.
