I have both LabVIEW 2013 64-bit and 2014 64-bit editions. I downloaded the "Control Design & simulation" module for both versions. However, it doesn't work. When I bring up the "controls" panel in the Front Panel or the "Functions panel in the Block Diagram and click on "Control Design & Simulation" tab, I find it empty. The LabVIEW components window shows that the CD Sim is already installed and acitivated. I attached a picture to explain what's wrong.
This module isderived from thecourse "Intro to Mechatronics" at Lawrence Technological University and was developed through seed funding from theCAAT. This module contains a PowerPoint presentation and LabVIEW simulation file. In the presentation the following concepts are discussed: wheel/tire-terrain interactive dynamics (wheel loads, effective rolling radius, and power balance),inverse dynamics-based control (changing rolling conditions and angular velocity control),control strategies (loops and algorithms), andcontrol algorithms in the LabVIEW environment.
The passive vibration isolation system has received considerable academic attention owing to its reliability. Zhang et al. developed a passive vibration isolation system using multiple coordinated dampers with a Stewart platform. The simulation proved that a vibration isolation effect of 28 dB could be achieved above 100 Hz; the resonance peak amplitude was approximately 4.27 dB [14]. Kamesh et al. designed a passive vibration isolator based on a folded beam that was experimentally validated; it could suppress vibrations above 30 Hz [15,16]. However, owing to their structural features, the passive platform is difficult to further improve vibrations at resonant frequencies. Therefore, semi-active vibration isolation techniques are also widely studied. Memet et al. developed a six-degree-of-freedom parallel isolated platform using a coil-over magnetorheological (MR) damper to reduce the amplification of resonant peaks by varying the damping of the system [17]. Xu et al. used electromagnetic springs to vary the equivalent stiffness of the system and, thus, the resonant frequency [18]. Semi-active vibration isolation reduces power requirements and improves stability. Both passive and semi-active control perform unfavorably for low-frequency, and the suppression effect at the resonant peak needs further improvement. If the performance of these platforms is improved by reducing the resonant frequency, it will lead to insufficient dynamic stiffness and affect the stability of the system [19].
In this study, a state-differential feedback control strategy with a disturbance observer (DOB)-based linear quadratic regulator (LQR) is proposed for further suppressing microvibrations to meet the vibration isolation requirements of an optical reference cavity. The manuscript is organized into four sections as follows: (1) the problems to be solved in this study, including the demand of the optical reference cavity and the equation of the individual vibration isolation module; (2) the design principle of the controller and the results of the simulation verification; (3) the experimental verification through the active vibration isolation system to confirm the feasibility and effectiveness of the designed controller; and (4) the summary of the main points of the study in the conclusion.
In this study, a state-differential feedback controller with a DOB-based LQR is proposed to meet the vibration isolation requirements of an optical reference cavity. The LQR controller was designed using the LMI method, and a DOB was developed based on the inverse function of the nominal model to estimate the disturbance force from the base platform. The simulation and experimental results showed that the controller had a significant suppression effect on the vibration and that adding the DOB could further improve the suppression effect. The experimental results also demonstrated that the maximum suppression ratios of the PSD in the Z-, X-, and Y- directions within 10 Hz were significantly improved. Compared to the disturbance source noise, the suppression rates of the root-cumulative PSD in the three directions were significant. The comprehensive vibration isolation performance met the frequency-stability standard of the laser. The effectiveness and feasibility of the controller for the vibration isolation of the optical reference cavity were verified. 2b1af7f3a8
