In my previous column, I showed bode plots for different types of transfer functions. I also touched on the basic principles of closed loop systems. As a refresher, the gain crossover frequency ...

In the last installment, we were halfway through the compensator design for a buck converter. As a quick recap, when designing digital compensators, the true system gain is different from the derived ...

Click here for the enhanced PDF version of this article including diagrams and/or equations. Compensation of switching power supplies is an essential element of proper and robust power design. The ...

Can we improve performance by adding control elements external to the PID loop? Yes. Here we consider torque control and the related subject of torque feedforward — which can make systems run more ...
