The paper presents the identification procedure for obtaining of transfer function model of an electrohydraulic power steering systems for low speed mobile machines. The single-input, multiple-output ...

This chapter presents fundamental concepts in control system analysis by transfer functions and analyzes digital systems constructed by open‐ and closed‐loop control methods. It also analyzes the ...

Open-loop systems may not be as smart as closed-loop systems, but they often shine in their simplicity. For the most part, they do what you expect them to do. Light goes on, light goes off.

Once the open-loop system and compensator have been designed, the loop gain transfer function can be estimated with Equation 25: (25) Equation 25 is based on Equation 13 and Equation 18. It’s ...

A motor-driven system has one pole in the open-loop velocity-transfer function, because kinetic energy is stored in the motor and load. ... an extra integrator is added to the open-loop system.

To perform the measurements, you inject a small AC signal into the power supply’s control-loop circuit and measure the loop’s gain and phase shift. By measuring the gain and phase, you can plot them ...
