Control System • Control is the process of causing a system variable to conform to some desired value. • Manual control Automatic control (involving machines only). • A control system is an interconnection of components forming a system configuration that will provide a desired system response. control system Output Signal Input Signal Energy Source

Types of Control system Open-Loop Control system utilize a controller or control actuator to obtain the desired response. Closed-Loop Control Systems utilizes feedback to compare the actual output to the desired output response.

General Control System Sensor Actuator Process Controller + Set-point or Reference input Actual Output Error Controlled Signal Disturbance Manipulated Variable Feedback Signal -

Control System Components System, plant or process To be controlled Actuators Converts the control signal to a power signal Sensors Provides measurement of the system output Reference input Represents the desired output

Examples on modern control system

A computer control system

Purpose of Control Systems Power Amplification (Gain) Positioning of a large radar antenna by low-power rotation of a knob Remote Control Robotic arm used to pick up radioactive materials Convenience of Input Form Changing room temperature by thermostat position Compensation for Disturbances Controlling antenna position in the presence of large wind disturbance torque
