There are many different types of control systems, but some examples include:
Feedback control systems: These systems use feedback from a sensor or process variable to adjust the control output to maintain a desired set point or condition.
Feedforward control systems: These systems use a predicted or measured disturbance variable to adjust the control output to prevent the disturbance from affecting the process variable.
Proportional-integral-derivative (PID) control systems: These systems use a combination of proportional, integral and derivative control actions to achieve precise control of a process variable.
Logic control systems: These systems use Boolean logic or other logical operations to make decisions and control processes. Examples include traffic lights, industrial robots and automatic washing machines.
Hybrid control systems: These systems combine multiple types of control systems to achieve a desired control performance.
Networked control systems: These systems use networks, such as Ethernet or wireless, to connect devices and exchange control information. These type of control systems are used in distributed control systems, such as smart buildings, power grids, and transportation systems.
