Abstract: 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.

Abstract: An improved system and method for analyzing motor performance to detect vibration of an electric machine controlled by a motor drive is disclosed. A load observer determines an estimated torque present as a load on the motor as a function of input signals corresponding to a desired torque to be generated by the motor and to a measured angular position of the motor during operation. The motor drive determines a frequency response of the estimated torque to identify at what magnitude and frequency any vibration components are present within the estimated torque signal. The motor drive compares the frequency response of the estimated torque signal to set points. If the measured magnitude of vibration at a particular frequency, as seen in the frequency response, exceeds a threshold set in one of the set points for that frequency, the motor drive generates an output signal indicting an excessive vibration is present.

Abstract: A system may include a power converter and a control system communicatively coupled to the power converter. The control system may determine a first DC voltage associated with the DC bus based on one or more DC external capacitance values that correspond to one or more loads coupled to the power converter. The control system may also determine a second DC voltage associated with the DC bus based on a capacitance of a system in which the power converter operates. The control system may also determine a third DC voltage associated with the DC bus based on the first DC voltage and the second DC voltage and adjust an operation of the power converter based on the third DC voltage.

Abstract: 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.

Abstract: 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.

Abstract: An improved system for tuning a motor controller 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.

Abstract: An improved system for controlling operation of a motor with a motor drive is disclosed. The motor drive includes a control module having an inner control loop operable to generate a torque reference signal and a load observer operable to generate an estimate of the torque present on the motor. The torque estimate is summed with the torque reference signal to generate a modified torque reference. The bandwidth of the load observer is set wide enough to generate the estimated torque over a desired operating range of the motor. The control module may also include a low pass filter and at least one tracking notch filter. The low pass filter suppresses vibrations at high frequencies, and the tracking notch filter suppresses resonances present at frequencies above the bandwidth of the load observer and within the pass band of the low pass filter.
