Control System Toolbox provides algorithms and apps for systematically analyzing, designing, and tuning linear control systems. You can specify your system as a transfer function, state-space, zero-pole-gain, or frequency-response model. Apps and functions, such as step response plot and Bode plot, let you analyze and visualize system behavior in the time and frequency domains.
You can tune compensator parameters using interactive techniques such as Bode loop shaping and the root locus method. The toolbox automatically tunes both SISO and MIMO compensators, including PID controllers. Compensators can include multiple tunable blocks spanning several feedback loops. You can tune gain-scheduled controllers and specify multiple tuning objectives, such as reference tracking, disturbance rejection, and stability margins. You can validate your design by verifying rise time, overshoot, settling time, gain and phase margins, and other requirements.
Create linear models of your control system as transfer functions, (sparse) state-space models, LPV and LTV models, and other representations. Discretize and resample models. Simplify analysis and control design by reducing model order.
Visualize system behavior in the time and frequency domain. Compute system characteristics such as rise time, overshoot, and settling time. Analyze system stability by computing gain and phase margins and crossover frequencies.
Interactively design and analyze single-input, single-output (SISO) controllers with the Control System Designer app, using automated tuning methods. Graphically tune common control components using root locus, Bode diagrams, and Nichols charts.
Design gain-scheduled controllers for nonlinear or time-varying plants. Specify requirements and automatically tune gain surface coefficients. Validate the tuning results across the entire operating range of your design.
Analyze and tune control systems modeled in Simulink and analyze its time and frequency domain characteristics using Simulink Control Design. Linearize Simulink models and compute time and frequency responses. Graphically or automatically tune feedback loops modeled in Simulink.

I was always wondering why I even have a LinkedIn account as I do very little next to nothing with it other than occasionally meeting with interesting people. That might be a mistake on my part but maybe this time I can use it for something that I'm excited about.
I'd like to share/promote an open source initiative that I was busy with for some time now, initially started as a hobby to teach myself Python. It is meant for control engineers/academicians who use control system toolboxes of various software suites but want to change their way to something more comfortable and more importantly permissive and convenient. If it sounds like something you might be interested carry on reading.
You shouldn't. If you are happy with what you have then you should keep using. This is not meant to be one of those "influential" LinkedIn nonsense. It is just an alternative that might be interesting for you.
This is an important (and valid) point that I might(!) convince you below. I started this as a gag to test my python skills with a grin on my face because I am not an expert programmer. As time passed by, that grin turned into a raised eyebrow. Because I was trying to find that point where I would just shrug and go: OK, that's too complicated to do. That would have also justified the existence of these extremely expensive and corporate software suites. However, that point never came and actually made me more skeptical about whether such point exists. Hence I've rewritten this tool a little better (limited by my coding skills) in order to release it out in the open. Put better: How I Learned To Stop Worrying and Love the Bomb.
Currently not much. But if you are having difficulties with finding a matlab license at work but don't like the alternative open source versions then this might become something relevant for you. See more at the license section.
The license is known as "MIT expat" license. The human readable version of the license can be found on TL;DR . Long story short: You can use it at work, school, home and so on, practically everywhere. If you make a product out of it, you just need to mention that you used it. That's it.
It is pretty early to use it as a daily tool. But depending on what you want to have it might even be ready. The whole point of this post is to find users and receive feedback about the features. Otherwise I'm catching myself coding strange academic stuff instead of possibly other things that is high-priority for industrial setting etc.
Touch. I am simply fishing for interested people. Coding and writing documentation simultaneously is hard for a single person. So mostly it is coding-documenting-coding-docu... anyway you get the point. Now it's documentation turn and I'm getting the hang of automated documentation creation stuff.
