Servo controllers commonly use traditional cascaded configurations in which a velocity loop is nested within a position loop. This configuration originated when current and velocity controllers were ...

Disturbance rejection, like command tracking, is usually expressed graphically. The graphs, called disturbance rejection plots, show the effect of PIV gains on disturbance torque applied to the shaft ...

Sponsored by Texas Instruments: Single-chip microcontrollers geared to servo and other industrial/EV control applications help engineers cost-effectively design multiple-axis systems. As manufacturing ...

Motion control systems, which normally control the position of actuator or stage, are at times given the task of providing both position and force control. These systems operate in a dual mode, in ...

To correct oscillations in a machine,mechanical design improvements and electronic filters are typically employed.However, these solutions often deliver limited success. Engineers should ...
