Read MoreUnderstanding Cascade Control and Its Applications For HVAC
Miles Ryan, a P.E. at QSEng authored this ASHRAE article published in February 2021. Most readers familiar with the operation of HVAC systems are aware of the term closed-loop control, oftentimes referred to as just a control loop, closed-loop, or feedback loop. Additionally, many will describe them as PID loops, short for Proportional-Integral-Derivative loops, although…
