You may have noticed PID Loop Analyzer’s version number creeping up. I fixed several bugs and greatly enhanced its performance over the last couple weeks. I am not ready to declare it bug free (I will never make such a bold statement.) but it passed my latest round of functional and performance tests. No one can find bugs faster than end users, however, so please report any bugs you encounter. I really appreciate all feedback.
I added one new feature, too: a simple report generator. Once you finish analyzing your control loop, click the Enter Data button and select Copy to Clipboard. Open your favorite text editor and paste (Ctrl V) PID Loop Analyzer’s report into it. The report contains fields to document the loop number and old PID tuning constants, and it documents the new PID tuning constants and process dynamics. An example follows:
