While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

PID (proportional, integral, derivative) control has existed for decades and there are many tools available to help implement PID to tune process control systems, thereby making it generally easy to ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Average current-mode control, as shown in Figure 1, is common in continuous-conduction-mode (CCM) power factor correction (PFC). It has two loops: a voltage loop that works as an outer loop and a ...

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...
