Thus the closed loop control system is Now say we need to cook a potato in a traditional microwave, the process would look like something below: Now, the potato being cooked depends on a lot of factors like the size of the potato, its freshness, etc. In and low torque output may be required to drive a load at low speed and high torque. Principles of feedback, transfer function, block diagrams and signal flow graphs, Steady-state Write the modeling equations for the mechanical systems shown in figure. A good example would be the control of simple traffic lights where the operation of each light depends only on a fixed time. The thermostatic temperature control in hour homes and public buildings is a familiar example. Feedback could increase the system gain in one frequency range and decrease it in another frequency range. In short, there is no feedback involved. being, hand muscle, eyes, thermometer such a system may be called manual feed back system. WebLECTURE NOTES 1 Why automatic control?
