The Oscillation of Electric Actuator

The applied force of electric actuators in trend can be chosen to challenge the station capability of the electric actuator model. The force ramps of electric actuator may cause breakaway and then return to a level below that of the normal friction. Additionally, an oscillation of the electric actuator is present and could be introduced by vibration and the response of friction model can be seen in the dynamic renders both in terms of sliding displacement and equation. The electric actuator nonlinear function also represents friction force as a function of velocity in steady state with remarkable dynamic properties in the friction model.

Results obtained from the electric actuator feedback control to positioning task simulations will enable us to have a good knowledge of the dynamic behavior for different electric actuator cylinders in order to see which features contribute to a better performance in a given engineering application. The electric actuator results aim to outline the faster response with oscillating in a range of actuator positions. Also, there are some problems to be solved such as the oscillations caused by electric actuator limit cycles should be expected to be around a certain desired position. It is a truth universally acknowledged that in many applications as robotics and aerospace engineering, the faster electric actuator response is one of the requirements for the positioning task so that we can design electric actuator positioning systems with smaller cylinder diameter. To be more specific, we may also increase the electric actuator supply pressure by obtaining necessary actuator force.

To solve this problem, we can use an optimal control design for nonlinear pneumatic actuators system and the friction compensation is especially important. In other words, according to scientific research results, if the electric actuator has an accurate response despite being slow, the results will be very good for some engineering applications as automatic machining processes. This is because the application requirements of electric actuator do not permit overshoot, and task velocity is smaller so we need to design electric actuator systems with larger damping rate and a classical feedback control system that largely depends on the necessary accuracy rate in application. The electric actuator dynamic behavior is similar to that in the chamber volume and does not have great impact on the positioning task in a full nonlinear model for electric actuator servo position system. It can be used in the case of mechanical design and control system design of different electric actuator industrial applications. However, the studies concerning the electric actuator do not address completely all the important nonlinearities in the model so further innovation and application results since the proposed systematic electric actuator is important to help users to achieve the precision control success.
