Copy of Motion Control with Voice Coil Actuator (VCA) - CPF Plant - on Wed, 07/01/2020 - 16:26 Designer231374 × Member for 4 years 11 months 2 designs 1 groups Add a bio to your profile to share information about yourself with other SystemVision users. https://explore.partquest.com/node/325890 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/325890"></iframe> Title Description <p>This example shows a VCA driven motion control loop that is acting through an equivalent model of a flexible mechanical structure. This model is shown on the right side of the schematic. It was calibrated to match a physical structure, based purely on its frequency response data and using the HyperLynx complex-pole fitting technology. The original mechanical model can be seen here: https://www.systemvision.com/design/spring-mass-structural-model-and-fitted-equivalent</p> <p>The top net in this schematic represents the displacement of an ideal position sensor, which provides the actual target position feedback. The loop compensation was designed by using "AC" or frequency-domain analysis of the open loop transfer function. The results are shown in the Magnitude and Phase difference plots (sensor_displacement - feedback). The loop crossover is seen to be at approximately 100 Hz, and the phase margin is just over 44 degrees. The corresponding time-domain step response is shown in the left-most waveform plot.</p> <p>You can see this same design and analysis using the original mechanical structural model for the "plant" here:</p> <p>https://www.systemvision.com/design/motion-control-voice-coil-actuator-vca-physical-plant</p> <p>You can see a more detailed model of this system, that includes the Power Electronics section (i.e. a PWM controlled MOSFET H-Bridge used to drive the VCA), here: https://www.systemvision.com/design/motion-control-vca-pwm-drive</p> About text formats Tags VCAMotion Control Select a tag from the list or create your own.Drag to re-order taxonomy terms.

An oscillator provides a sinusoidal excitation signal to the primary winding of the LVDT. The differential secondary winding outputs are rectified and low-pass filtered. The difference voltage, which is proportional to the mechanical displacement of the LVDT core, is the measurement result.</p> <p>This virtual prototype can be used to select the low pass filter frequency, so it is low enough that the oscillation frequency is mostly removed from the output signal, yet high enough to track the natural frequency of mechanical system the sensor is intended to measure. It can also be used to analyze parasitic effects, such as the resistance of the wires connecting the sensor to the signal conditioning circuits. This resistance affects the output voltage and therefore corrupts the measurement results. Likewise, the non-linear behavior of the rectifier diodes affects the linearity of the position measurement.This can be seen if the force input is slowly ramped from -1000N to 1000N over a 1 second interval.</p> About text formats Tags LVDTDisplacement sensorPosition sensorrectifierMechatronicsMotion Control Select a tag from the list or create your own.Drag to re-order taxonomy terms.

That means you can change important system design parameters, including the battery voltage and the current sense resistor value, as well as key electrical characteristics of the solenoid. After making a change, just push the green "Play" arrow and a new simulation will be run ... after a short time, you'll see its effect on the system response. For example, if you change the stroke to 5m (meters) and t_response to 10m (seconds), to model a larger and heavier solenoid, this will significantly alter the current sense (v_cs) "signature" coming from the NCV84160.</p> About text formats Tags solenoidNCV84160Motion Control Select a tag from the list or create your own.Drag to re-order taxonomy terms.
