Version 3 beta 5

This is a beta version. Some things are missing, like the help content. Also, the program has not been tested extensively. It may have some bugs.

New features of this version

• Added the possibility to plot the frequency response in Hz or rad/s and magnitude in dB or gain factor.
• Fixed bug with enable and disable checkboxes in transfer function definitions.

Version 3 beta 4

This is a beta version. Some things are missing, like the help content. Also, the program has not been tested extensively. It may have some bugs.

New features of this version

• Added a Tmax (max time simulation value) spinbox at the system definition window.
• Removed the r(t) and w(t) maximum instant value limitation. Now if the r(t) or w(t) instants are larger than Tmax, a warning is issued.
• Added some help content for non-linear system definition.
• Fixed some bugs in the non-linear system string parser.

Version 3 beta 3

This is a beta version. Some things are missing, like the help content. Also, the program has not been tested extensively. It may have some bugs.

New features of this version

• Fixed issue #41

Version 3 beta 2

This is a beta version. There are some things missing, like the help content. Also, the program has not been tested extensively. It may have some bugs.

New features of this version

• Added cursor lines in the plot areas.
• Added saturation effect to the discrete system simulation.
• Improved non-linear system parse string.
• Stability margins can be drawn in the bode plot.
• Added hidden system definition save and import.
• Added help window.
• Fixed issues #39 #38

Version 3 beta 1

This is a major update from LabControle 2.

This is a beta version. There are some things missing, like the plot of stability margins in Bode diagram. Also, the program has not been tested extensively. It may have some bugs.

Known bugs

• Bode plot magnitude is drawn with the wrong log function. Inadvertently the log function (base 'e', ln) was used instead of log10 (base 10).

New features of LabControl 3

• The user can handle multiple system definitions. A list of systems has been added in the program interface.
• The user can plot multiple time domain and frequency domain simulations. Iterative lists in the interface makes it possible to select which signals to plot.
• The plotting of the Nyquist diagram has been improved.
• In the time domain response, the control action signal is now available to be plotted.
• Use of the Controls module to handle transfer functions and solve systems (for continuous linear systems).
• Complete re-structuring of the internal data structure.
• Improvement of the user interface.
• New way of configuring the inputs for time domain simulation

Notas dessa versão:

• Código atualizado para Python 3 e pyQt5.
• Alguns bugs corrigidos.

Versão 2.2 beta 1 do LabControle

Notas dessa versão:

• Nova funcionalidade: ao clicar em um ponto sobre as curvas dos gráficos de simulação e diagrama de bode um ponto é mostrado e a sua coordenada é mostrada na toolbar do gráfico. O usuário pode avançar ou retroceder o ponto usando o scroll do mouse.
