摘要： A system includes a motor configured to be coupled to a non-rigid load and a control system disposed within, or communicatively coupled to, a drive system configured to control an operation of the motor. The control system includes a processor and a memory accessible by the processor. The memory stores instructions that, when executed by the processor, cause the processor to generate a smooth move input profile to control the operation of the motor based on inputs specifying a desired operation of the motor, apply a notch filter having a notch filter frequency to the smooth move input profile to produce a filtered smooth move input profile, and send a command to the drive system based on the filtered smooth move input profile, wherein the command is configured to adjust the operation of the motor.

摘要： A system and method for online simulation of a controlled machine or process utilizes a simplified model of the system dynamics and may be used with hardware in the loop to evaluate performance of the controlled system or with software in the loop to perform commissioning of the control program prior to completion of the mechanical installation. The simplified model includes dominant order dynamics of the controlled system such as the inertia of the system and a damping factor. Further, the online simulation is scheduled to execute at an update rate slower than the update rate of the control loops within the motor drive. The simplified model and reduced update rate reduce the computational burden on the processor such that the simulation may be performed either on the industrial controller or on the motor drive.

摘要： An improved system and method for tuning a motor controller is disclosed. The improved system and method for tuning a motor controller adjusts controller gains and filter settings in tandem to achieve a desired level of performance. A user terminal is in communication with a motor controller and reads the existing controller gains from the motor controller. The user terminal displays the existing controller gains and at least one user selectable object for adjusting the controller gains. A user adjusts the user selectable object to adjust the controller gains in tandem. The controller gains are adjusted responsive to the user input while maintaining existing relationships between controller gains. The user terminal writes the adjusted values of the gains to the motor controller.

摘要： Various embodiments of the present technology generally relate to condition monitoring in industrial environments. More specifically, some embodiments relate to an embedded analytic engine for motor drives that monitors induction motor conditions for potential failures including rotor faults and stator faults. In an embodiment, a condition monitoring module is configured to obtain runtime signal data from a controller within a drive, derive runtime metrics from the runtime signal data based on an induction motor fault condition, provide the runtime metrics as input to a machine learning model constructed to identify a status of the induction motor based on the runtime metrics and output the status, and monitor the induction motor fault condition based on the status of the induction motor output by the machine learning model.

摘要： An improved system for tuning a motor controller (10) is disclosed. The controller gains are initially set based on the measured frequency response for the controlled system. A desired level of performance is defined by setting a desired phase margin and a desired gain margin to be observed in the frequency response. An improved method of determining the frequency response provides for a reduced computational intensity. The initial tuning routine uses the frequency response to set not only controller gains, but also settings for filters in the control module. Having obtained the desired level of performance from the initial tuning, the motor drive executes an adaptive tuning routine while controlling the motor. The adaptive tuning routine tracks changes in the operating performance and adjusts the filter settings or the controller gains to return operation to within the desired level of performance while the motor continues to operate.
