What is the formula of the law of conservation of mechanical energy?

The formula of the law of conservation of mechanical energy is K + U = constant value, which means that the total mechanical energy (sum of kinetic energy and potential energy) of the system in a closed system remains constant, that is, kinetic energy and potential energy can be converted into each other in the system, but the total mechanical energy always remains unchanged.

What is a gyroscope used for?

A gyroscope is an inertial sensor used to measure angular velocity or angular displacement. They are widely used in aerospace, automotive, robotics, VR/AR and consumer electronics. The working principle of a gyroscope is based on the conservation of angular momentum, producing a torque proportional to the angular velocity, thereby measuring rotation. They can be divided into mechanical gyroscopes, MEMS gyroscopes and fiber optic gyroscopes, with accuracy and sensitivity varying depending on the application. Gyroscopes are also used in fields such as medical, industrial automation and motion capture.

What control is pid?

PID control is a feedback control mechanism that measures the error and calculates the control output to bring the controlled variable close to the set point. It is based on three basic operations of proportion, integral and differential, which are used to quickly respond to errors, eliminate steady state errors and improve system stability respectively. The PID controller includes an error calculator, a PID controller and an actuator, and parameters such as proportional gain, integral gain and differential gain need to be adjusted according to the controlled process. The advantages of PID control include high control accuracy, good stability, easy implementation and adaptability to various processes. However, the disadvantages are that it may oscillate, be sensitive to parameter changes, and is difficult to implement in nonlinear systems.
