Frequency Analysis Software (FAS) allows tuning of servo control systems
in the frequency domain, which is often preferred for systems with
resonances or when the design engineer is comfortable with classroom
control theory.
According to the company, while in most cases tuning servo systems in the time domain works well, this software provides an alternative. Used in conjunction with the company’s motion controller, it measures the frequency response of the plant to be controlled. It simulates the possible control solutions and synthesizes the two to allow for Bode analysis of the closed loop system and allows the designer to try various simulations of the controller parameters such as the PID filter and notch parameters and combine them with the plant to give the open loop frequency response. FAS software is available for the company’s DMC-41x3 Econo and DMC-40x0 Accelera motion controllers.
