  • Servo Control of a DC Brush Motor
    of the PIC17C42 as a DC brush motor servo controller. It is shown that a PID (Propor-tional, Integral, Differential) control calculation can be performed in less than 200 ms (@16 MHz) allowing control loop sample times in the 2 kHz range. Encoder rates up to 3 MHz are easily handled by the PIC17C42's

  • Special ICs
    , and uses that value for system damping. Because the derivative is proportional to velocity, the need for velocity feedback from a tachometer is eliminated. Recently developed servocontrol chips, called the LM628 and LM629, contain PID filtering functions. Filter constants can be changed
  • DSPs: Smarter than your average chip
    are steadily introducing DSPs into motor controls. "An engineer can design a digital motor controller with a DSP that costs as little as $2," says Leon Adams, DSP manager at Texas Instruments. Many of the fundamental algorithms used in motor control such as pulse-width modulation (PWM) and PID can
