Dynamic Systems and Control
Mohammed Dahleh, Munther A. Dahleh, and George Verghese · Massachusetts Institute of Technology
The text addresses dynamic systems, i.e., systems that evolve with time. Typically these systems have inputs and outputs; it is of interest to understand how the input affects the output (or, vice-versa, what inputs should be given to generate a desired output).
