Hey GuysI'm designing some stuff for controll theory

There I met following problem:

I want calculate the matrix A which is the product of X and G.

A is 6x6 matrix and all values in the diagonal are ones, the rest is undefined and should be calculated

X is 6x6 diagonal matrix with the values X1...X6

and G is also 6x6 and have all these values.

now I'm stuck 'cause I haven't used Maple frequently (only some simple stuff up to now, nothing with matrices)

I'd really appreciate it, if someone can tell how to tackle this problem

Cheers

Recently I started to learn to use maplesim. I wanted to set up a feedback system which is used to control the speed of DC motor. I don't know how to build it. Please give me some advice. I really appreciate your help.

im interested to know if there are developed MapleSim examples of water level control in a tank

Hi there,

I would like to introduce my self and ask you for an advice.

I have a four linked robot that i would really like to control by the meaning of the optimal control theory. The arm has 4 actuators (giving torques U) in corrispondence of 4 rotational joints. P parameters describe the system.

I got ht edynamic system with the Lagrangian method and now I have 4 2nd order...

Hello all,

I'll be straight-forward.

I have Maple 15+MapleSim 5. I don't have Control Design Toolbox. I want to embed a linearized system object as an msys file into MapleSim.

The Linearization template failed to create the file. I tried to use the codes in the template directly as code in Maple, but also failed. Seemingly because I don't have Control Design Toolbox in which the code need to load.

I have been googling around with no avail. I...

We have just released a free collection of Maple and MapleSim classroom materials that helps bring modern technology to any introductory course in control design. This collection includes interactive classroom demonstrations that illustrate key concepts; lab projects and assignment questions; and example models ready to be explored. It’s been designed primarily for instructors, but students should find much of it useful, too.

Typically, plots on a Maple worksheet fill substantial portions of the printed page when they're printed out. What I'd like to do is resize plots, prior to printing, such that they're smaller when printed. I'd also like all plots on a worksheet to print out at the same size. Note that simply highlighting a plot on the Maple worksheet and then pulling the corner to resize it, is not what I want to do: I find it very difficult to anticipate the...

Hi,

I am trying to implement some numerical algorithm for an optimal control problem (still).

It involves double cycle. In the inner one two DE systems are solved sequentially and the result is used to update values of some objective function.

This part uses remeber option thanks to pagan and is ok.

However, in the outer cycle I use the values of this objective function to obtain solution for yet another DE and update ICs for the inner cycle.

Well,

Basically I know that.

I just hoped there is some walkaround this problem.

It seems now there is not.

The problem I am trying to solve is how I can construct an iterative procedure where function is computed from numerical solution of the ODE system (done) and then this very function is used to recalculate the solution of this ODE system.

This is my attempt to impement some sort of gradient projection method to the optimal...

Hi everyone.

I am currently trying to write the gradient projection algorythm for an optimal control problem with Maple.

This involves calculation of the gradient of the objective function at every new iteration, which would be not a problem per se. However, in optimal control problem this last depends on state and costate variables which, in turn, are given by the system of ODEs. This system is solved numerically only. As far as I understood Maple is recalculating...
