O N E Introduction ANSWERS TO REVIEW QUESTIONS 1. Guided m issiles, autom atic gain control in radio receivers, satellite tracking antenna 2. Yes - power gai n, rem ote cont rol, param eter conversi on; No - Expense, com plexity 3. Motor, low pass filter, inertia supported between two bearings 4. Closed-l oop sy stems com pensat e for di sturbances by measuri ng the response, com paring it to the input response (t he desi red out put), and t hen correct ing the out put response. 5. Under t he condi tion that the feedb ack elem ent is other than unity 6. Actuating si gnal 7. Multiple subsystem s can time share th e controller. An y adjustments to the controller can be implemented with simply so ftware ch anges. 8. Stability, transient respons e, and steady-state error 9. Steady-state, transient 10. It follows a growing transient response until th e steady-state response is no longer visible. The system will either destroy itself, reach an equilibrium state b ecause of saturation in driving amplifiers, o r hit lim it sto ps. 11. Transi ent response 12. True 13. Transfer function, state- space, differential equations 14. Transfer function - the Laplace transform of the differential equation State-space - represent ation of an nt h order di fferen tial equat ion as n si multaneous fi rst-order different ial equat ions Differen tial eq uation - Mo deling a system with its d ifferen tial eq uation SOLUTIONS TO PROBLEMS 1.
