State analysis modeling program

Abstract

Modern day control systems, utilizing a digital computer, contain samplers as well as linear and nonlinear elements. State space techniques are the best means for analyzing systems of this type.

SAMP (State Analysis Modeling Program, SAMPler), a digital computer program, uses these techniques in order to provide the following:

1. SAMP is capable of analyzing a system containing integrators, summing junctions, fixed gain terms, samplers, and a variety of nonlinearities.

2. Samplers can be the zero order hold type or the finite width type. They can operate at different rates.

3. A novel feature of this program is utilizing a high speed sampler for simulation of nonlinearities.

4. SAMP's inputs are essentially the matrices required for a state space analysis. They include the system coefficient matrix (A), the state transition matrix (B), the initial state vector (W), and a novel specification matrix (C).

S. The program contains built in diagnostics designed to aid the user troubleshoot his program setup.

6. Primary program output is a print/plot of any state variable versus time. If selected the status of all state variables versus time will be printed.

7. SAMP contains a built in example designed to aid the user understand program operation.
