Sensor Selection for Mechatronic Systems Based on Closed-Loop Control Simulations

The goal of the paper is to present a tool, which can be used for the selection of sensors in a closed-loop control of a mechatronic system. Several sensor parameters (such as noise power or delay) are simulated and their effects on the whole system’s performance are analyzed. For the simulations, Matlab-Simulink environment is applied. The simulated data are then used to estimate the transfer function of the whole closed-loop system with a controller. The services of the System Identification toolbox are appropriate for this task. If the specifications are given as the required damping and bandwidth of the system, the tool estimates the sensor parameters, which can ensure the desired performance. Some simulation results demonstrate the workflow of our tool, which was implemented using the App Designer of Matlab.
