ControlSystems.jl is a Julia toolbox for control systems design and analysis, offering models in transfer-function and state-space representations, enabling construction of complex systems, simulation in time and frequency domains, and performance/stability evaluation. This toolbox works similar to that of other major computer-aided control systems design (CACSD) toolboxes. Systems can be created in either a transfer function or a state space representation. ...

RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and...

Script for Maxima that analyzes analog filter circuits. Reads a netlist (e.g. LTspice) and calculates the symbolic transfer function. Supported components: R, L, C, voltage, current, opamp

This Projects target is to visualize the properties of Control-Systems. One can insert the roots of the caracteristic Equation and plot the Locus by varying the Parameters. One can insert the transfer-function and view the changing response by varying the parameters. This applies also to the Bode-Plot. All those Plots can apply to the same Control-System and are updated in Realtime.

Script for Maxima (a Computer Algebra System) that performs symbolic analysis of analog integrated circuits. Script allows to find approximated poles and zeros of transfer functions, developed and optimized for transfer functions of amplifiers, but can be used also for any general analog circuit. The script calculates DC transfer function, zeros, poles and creates Bode plots. DC transfer function, zeros, poles result simplified so main contributing elements can be easily identified. Poles and zeros approximation principle mainly taken from the paper "INDIRECT FEEDBACK COMPENSATION TECHNIQUES FOR MULTI-STAGE OPERATIONAL AMPLIFIERS" by Vishal Saxena Usage examples also can be taken from "Maxima Opamp Analisys" project Any comments bug reports and improvement suggestions are welcomed! ...

The developed graphical interface is based on the SKILL language which is a Lisp dialect used as a scripting language and PCell (Parameterized Cells) description language used in many EDA software suites by Cadence Design Systems.
