Field-oriented control (FOC), for example, uses a single-cycle MAC with data saturation as well a zero overhead looping and barrel shifting for high performance speed, position, and torque control.

For this unit, the PID controller board needs to output a 12-V PWM signal to control motor speed, and use an analog-to-digital converter (ADC) channel to sense the position of the actuator.

Generally, one set of crosshead position PID control gains on a static testing machine will generate acceptable crosshead position control over almost the complete speed range of the machine. A second ...
