## Discrete-Time Control SystemsThe new edition of this comprehensive digital controls book integrates MATLAB throughout the book. The book has also increased inflexibility and reader friendliness through the streamlining of coverage in Chapters 6 7 (controllability, pole placement and observability, and optimal control). The previous edition ISBN is: 0-13-216102-8. |
