GnuGPL 2002-2005 Loreto Parisi
Control System Toolbox (CST) for TI-89 is a suite of functions and programs for Systems Control and Tuning for the TI-89 personal calculator, developed by Loreto Parisi starting from June 2002.
CST supports Linear Time-Invariant (LTI) Systems in Continuous(t)and Discrete (k) Time Domains simultaneuosly, Delayed Systems (affected by a Time Delay) and Non-Linear Systems (to be linearized).
CST defines systems by Transfer Function or State Space and converts Continuous Time to Discrete Time Systems using known discretizations methods.
CST performs Time Domain and Frequency Analisys, supported by Laplace and Zeta transformations, Bode and Step Response Diagrams.
CST verifies Open-Loop and Closed-Loop Stability by Eigenvalues (and Eigenvectors) calculations, Routh Matrix and Conditions, Gain and Phase Margins evalutations, Root Locus and Nyquist Diagrams plottings.
CST supports Feedback Control Systems Design, Analisys and Tuning, providing P, PI, PD, PID and Lead and Lag Networks Design (even using Nichols maps), Ziegler-Nichols closed-loop Tuning, Optimal Control with ISE, ISTE and IST^2E, Adaptive Filtering, Closed-Loop Gain and Phase Margins evalutations, Time Domain analisys against custom inputs and noises.
CST operates Direct Laplace and Zeta Transformations and Inverse Laplace and Zeta Transformations.
CST loads and saves working sessions at any time, safing you to loose data quitting CST. It saves separately significant data (such as Transfer Function and Step Response) and plots (such as Bode and Nyquist Diagrams).
CST has a robust Error Management System to prevent unsafe aborts and a usefull On-line Help.
What Else?

- Which Texas Instruments calculators are supported? The currently supported TI calculators are TI-89, TI-89 Titanium and TI-92/Plus/Voyage 200.
- How to fix the DOMAIN-ERROR on TI-89 Titanium? This is a known issue that happens on the TI-89 Titanium series calculators. To solve it please do
Mode -> page 2 -> Exact/Approx change from "Exact" -> "Auto"
Here you are a complete list of Control System Toolbox r1.3 embedded and external tools.
From release 1.3, CST needs the tool LZT to perform symbolic calculations (i.e. Laplace and Zeta transforms). To install LZT please follow instructions we provide in section Install LZT of CST Start Guide. We also raccomend to read the LZT Readme file.

This powerful tool needs any kernel like DoorsOS, UniOS or KerNO. We provide KenNO r3.1 from CST r1.3 as its convenient installation. To install KerNO please follow instructions we provide in section Install KerNO of CST Start Guide. We also raccomend to read the KerNo readme file.

The best program for TI calculators that trace frequency plot of a transfer function W(s) of a SISO or MIMO system (Bode plots) with or withoout time delay. BodeX use a powered routine to plot the phase plot of a transfer function (don't use simply the angle(•) function). The BodeX routines ensure the correct phase plot any W(s) it's plotted.
