28 Apr 2011 anti-windup PID controller - SIMULINK block This SIMULINK block contains a PID controller with anti-windup Author: Paul Acquatella

Arkadiy, thanks a lot for your comments and documentation.

I guess this simple submission will now work as an "academic" example of understanding the basics of anti-windup. Moreover, for more complex control structures, other forms of anti-windup can be implemented.
30 Jun 2009 Maximum Drawdown Maximum relative drawdown of time-series data Author: Andreas Bonelli

I think this version is more practical and quite better than Steiner's. Also, is faster since it does not computes the whole drawdown vector (which I don't need in particular) and its more understandable. Advantage vs. MATLAB's routine: data can be <= 0, and still computes (i.e. MaxDD = 120%, for instance).

28 Apr 2011 anti-windup PID controller - SIMULINK block This SIMULINK block contains a PID controller with anti-windup Author: Paul Acquatella Turevskiy, Arkadiy

Couple of additional comments:
1) PID Controller block in Simulink has an option to turn anti-windup protection on. Here is the doc for this block:

22 Dec 2009 anti-windup PID controller - SIMULINK block This SIMULINK block contains a PID controller with anti-windup Author: Paul Acquatella Turevskiy, Arkadiy

Thanks for an interesting submission.

Starting with R2009b Simulink includes PID Controller block that supports integrator anti-windup. If you are interested in designing and tuning PID controllers in MATLAB and Simulink, please take a look at new PID tuning capabilities shipped in Simulink Control Design in R2009b:

There is also a webinar on the subject:
