TrueTime: Simulation of Networked and Embedded Network Sys

TrueTime is a Matlab/Simulink-based simulator for real-time control systems. TrueTime facilitates co-simulation of controller task execution in real-time kernels, network transmissions, and continuous plant dynamics. Features of the simulator include

• Written in C++ MEX, event-based simulation
• External interrupts
• Possibility to write tasks as M-files or C++ functions. It is also possible to call Simulink block diagrams from within the code functions
• Network block (Ethernet, CAN, TDMA, FDMA, Round Robin, and switched ethernet networks)
• Wireless network block (802.11b WLAN and 802.15.4 ZigBee)
• Battery-powered devices, Dynamic Voltage Scaling, and local clocks
• Stand-alone network interface blocks

Mobile robots simulators

I am trying to build a list of simulators for mobile robots

MissionLab v7.0 (last release 07/12/2006)
Developed at Georgia Tech
MissionLab takes high-level military-style plans and executes them with teams of real or simulated robotic vehicles

Bungee jumping example

Here is a nice step-by-step example on how to determine which cord is the best for bungee-jumping depending on its spring constant.

Tutorials Simulink

A great page that lists different tutorials:
http://www.mathworks.com/academia/student_center/tutorials/simulink-launchpad.html

If you are unfamiliar with Simulink, you can start with Getting Started Video Tutorial, that introduces Simulink and presents its key features.

For further understanding, Mathworks offers an Interactive Simulink® Tutorial composed of several components. You need to register for it, but it takes only a few minutes and you have immediate access to it. The modules of interest:

Simulink On-Ramp (approximately 45 minutes)
Learn the basics of graphical modeling with Simulink.

-Introduction: What is Simulink? (3:17)
Introduces the basics of Simulink, its applications, and the tutorials
-Constructing and Running a Simple Model (13:37)
Cover the basics of constructing a simple model and changing block parameters
-Simulating a Model (10:58)
Understand how Simulink propagates signals in time and manage how it simulates
-Working with MATLAB® (9:07)
Pass data between Simulink and MATLAB
-Creating Subsystems (6:44)
Simplify your model by grouping blocks into subsystems

Using Simulink to Model Dynamic Systems (approximately 30 minutes)
-Modeling Transfer Functions (12:50)
Implement a derived transfer function, and understand how Simulink propagates a continuous dynamic system through time
-Modeling a System of Differential Equations (7:26)
Learn to use the integrator block to model differential equations
-Applying System Modeling to Controls (5:19)
Implement closed loop systems and its application to controls

Simulink

Simulink® is an environment for multidomain simulation and Model-Based Design for dynamic and embedded systems. It provides an interactive graphical environment and a customizable set of block libraries that let you design, simulate, implement, and test a variety of time-varying systems, including communications, controls, signal processing, video processing, and image processing.
