EEL4657 - Dr. Haniph Latchman Chapter 1 Solutions 1. (a) 10 applications of control systems: - HVAC building control systems (temperature, humidity, and pressure) - Unmanned vehicles (planes, cars, army tanks) - Automobile cruise control system - Robotic applications - Coordinated control system for boilers and generators in power plants - Motor systems for computer disk drives - Motor fins used for ship stabilization systems - Construction machinery (drills, forklifts, compactors) - Climate control feature in automobiles - 2. A Servo is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending the servo a coded signal. As long as the coded signal exists on the input line, the servo will maintain the angular position of the shaft. As the coded signal changes, the angular position of the shaft changes. In practice, servos are used in radio controlled airplanes to position control surfaces like the elevators and rudders. They are also used in radio controlled cars, puppets, and of course, robots. 3. (a) Stability - BIBO is the most widely used definition for stability with re- spect to control systems. A system is said to be stable if for every bounded input, the output is bounded (b) Performance - the objectives for performance include: -Fast response to correct undesired behavior
