Mechatronics System Components
- The mechanical system receives input signals (physical quantities).
- The electrical system converts these signals into electrical signals, through sensors.
- These electrical signals are then conditioned and processed into a suitable format by amplifiers, filters, and converters.
- The controller (microcontroller, or programmable logic controller) receives these conditioned signals.
- The controller uses these signals to execute control instructions.
- The controller sends output signals through amplifiers and actuators, influencing the mechanical system.
- The mechanical system's response is then measured via sensors, forming a closed loop feedback system.
- The user interface provides inputs to the system, such as keyboard, mouse, touchscreen or buttons and displays outputs to the user via LCD, LED, or monitors.
