Opening and using a modelica model on MapleSim
http://www.mapleprimes.com/questions/202069-Opening-And-Using-A-Modelica-Model-On-MapleSim?ref=Feed:MaplePrimes:Tagged With MapleSim
<p>Hello,</p>
<p>I would like to open a modelica model with MapleSIM. When I do "import modelica", I received the error message : "import failed : no library found".</p>
<p>I believed the modelica library was already installed on maplesim but may be not. Do I need to install modelica library ? and if yes, how ?</p>
<p>More generally speaking, how can I do to open a modelica model on maplesim?</p>
<p>Thank you for your help.</p><p>Hello,</p>

http://www.mapleprimes.com/questions/201855-Piecewise-Constant-Interpolation-Table?ref=Feed:MaplePrimes:Tagged With MapleSim
<p>I have some data for a model in MapleSim that I would like to use a time look up table with. I've found that the two options for interpolation are linear and 1st derivative, but the data was intended to be interpretted as piecewise constant. Is there any way to acheive this option in MapleSim?</p><p>I have some data for a model in MapleSim that I would like to use a time look up table with.

http://www.mapleprimes.com/questions/201848-Fluid-Media-Coverage?ref=Feed:MaplePrimes:Tagged With MapleSim
<p>Does MapleSim 6 cover temperature dependent fluid media? In the modelica standard library (MSL), there is for example a medium model for T-dependent properties, defined by tables or polynomials (Modelica.Media.Incompressible).</p>
<p> </p>
<p>Is it included in MapleSim 6 or can be somehow modelled?</p>

<p>Hi All. Hope all is well.</p>
<p>Assume that we have partitioned [0,a], into N equidistant subintervals and in each subinterval we have M sets of polynomials of arbitrary form[say b<sub>ij</sub>(t)](a.e Taylor series, or Bernstein series,…)</p>
<p>for Example with N=4, M=3 and by Taylor series we have:</p>
<p> <img src="/view.aspx?sf=201743_question/Untitled.jpg" alt=""></p>
<p>now we want to approximate a function, asy f(t), in this interval with following form:</p>
<p> <img src="/view.aspx?sf=201743_question/2.jpg" alt=""></p>
<p>If we have:</p>
<p><img src="/view.aspx?sf=201743_question/3.jpg" alt=""></p>
<p>(Tau is a constant number)<br> then: How can we find L and Z matrices using maple? Is it any way? (or other softwares?)</p>

<p><strong><span>Hollywood Math (with more new examples!)</span></strong></p>
<p><span>Over its storied and intriguing history, Hollywood has entertained us with many mathematical moments in film. John Nash in “A Beautiful Mind,” the brilliant janitor in “Good Will Hunting,” the number theory genius in “Pi,” and even Abbott and Costello are just a few of the Hollywood “mathematicians” that come to mind.</span></p>
<p><span>Although the widespread presentation of mathematics on the silver screen is not always entirely accurate, it does serve as a great introduction to the study of mathematics in general. During this webinar Maplesoft will present a number of examples of mathematics in film. See relevant, exciting examples that you can use to engage your students.</span><span>At the end of the webinar you’ll be given an opportunity to download an application containing all of the Hollywood examples that we demonstrate.</span></p>

<p><span>The following examples will be demonstrated:</span></p>
<p><span>• PID Control</span></p>
<p><span>• LQR, Kalman filter design </span></p>

http://www.mapleprimes.com/questions/201527-How-Can-I-Precalculate-Appropriate-Initial?ref=Feed:MaplePrimes:Tagged With MapleSim
<p> I have a complex set of mechanical linkages and components, and I am trying to create a feedback control system for trajectory-tracking with the end-effector. They system is driven by a set of prismatic joints (representing ideal series-elastic actuators). At this stage I am simply trying to establish the control parameters and the required forces to achieve desired positions/velocities in the workspace, and have not yet inserted any realistic actuator characteristics.<br><br>An open-loop solution can be found using translational position control on the prismatic joints, this is no problem. However to close the loop properly, I need to convert the system to use a differential input, such as a velocity driver. At this point everything becomes very finicky and highly dependent on initial conditions. Generally Maplesim gives up, claiming that no solution can be found. Due to the complexity of the system, there is no way for me to guess a priori the appropriate initial conditions of all the joints and linkages. I was wondering if anybody had any tips for either pre-determining the initial parameters, or alternatively for relaxing the solver in some way to allow for a wider exploration of possible solutions. Or any other ideas!<br><br>So far: I have tried setting up an open loop position-driven system with the same trajectories and using Maple to read all the initial conditions, then transferring them as guesses to my closed-loop system. But this has not worked. As a temporary workaround I am using position drivers on the SEAs, which are in turn driven by a velocity controller (with an integrator term). However this is suboptimal. Any help would be much appreciated!</p><p> I have a complex set of mechanical linkages and components, and I am trying to create a feedback control system for trajectory-tracking with the end-effector.

<p>Hi, this question is for Samir Kahn or other maplesoft staff.</p>
<p>Is there a way to use modelica biochem or any other chemical path library into maplesim? Do you plan to integrate this library in future versions of maplesim? Wolfram systemModeler has this library already integrated as does symbiology in matlab. Mr Kahn, I hope that your background in chemical engineering help you push for this new development in maplesim and help this product be even better than the competion. thank you and let me know as soon as possible.</p>

<p>Hi</p>
<p>I want to create a linearied model for a single or multi degree of freedom vibration system by MapleSim. i faced a lot of problem such as causalize ports, i search the user manual but i didn't find it useful. i attach a very simply one degree of freedom vibration system. i wondering if every one create a linearized model for it. my final goal is governing the equation and determine the natural frequency with nyquist plots. i have mapleSim 6.2 and Maple 17.

<p>MapleSim 6.4 includes more powerful tools for creating custom components, performance enhancements, and enhancements to the model generators for Simulink® and FMI. </p>
<p>We have also made important updates to the MapleSim Control Design Toolbox. This toolbox now offers a more complete set of algorithms for PID control, new commands for computing closed-loop transfer functions, and numerous improvements to existing commands. These enhancements allow engineers to design a greater variety of controllers and controller-observer systems while taking advantage of the greater flexibility and analysis options available through the use of symbolic parameters. </p>
