servomehaanikas

Servomehaanikas is an interdisciplinary field that studies and designs systems that control motion precisely through feedback, typically using servo mechanisms. The field combines concepts from control theory, electronics, mechanical design, and computer-based automation.

A typical servomehaanikas setup includes an actuator (such as an electric motor, a hydraulic or pneumatic cylinder), a feedback sensor (encoder, potentiometer, resolver), a controller (analog or digital), and a drive or gearing arrangement.

Operating principle: a reference input defines the intended position or speed; a sensor measures the actual output; a controller computes the error and issues commands to the actuator to reduce the error, forming a closed-loop system.

Common types of servomehaanikas control are position, velocity, and torque control. The actuator options range from brushless DC motors and servo motors to linear actuators and hydraulic/pneumatic cylinders.

Performance considerations include resolution, accuracy, repeatability, speed, and control bandwidth. Design challenges involve friction, backlash, stiction, thermal drift, wear, and nonlinearities in mechanical transmission.

Applications span robotics, computer-numerical-control tools, automated manufacturing, aerospace actuators, pick-and-place equipment, and camera autofocus systems.

Historically, servomehaanikas emerged from the broader development of automatic control and mechatronics, integrating feedback sensing, control algorithms, and actuation to deliver precise motion. It remains a core element of robotics and automated systems.
