Greg: For unmeasured load disturbances on a process input, the proportional-integral-derivative (PID) algorithm has been shown in practice and proven in theory to offer the best performance in terms ...

Peter Morgan, what are points of confusion that you resolved in the PID Algorithms section? Peter: While the PID algorithm in its various forms has been the workhorse of virtually all closed-loop ...

Finally, the optimized SSA-fuzzy PID control algorithm is validated in a simulated environment and subjected to optimal control performance testing in practice. The experiment focuses on the systems ...

The above discussion suggests the benefits of adding feed-forward terms to the control algorithm, but a second derivative term (D2) can also be added to the PID which results in a PID + D2 + feed ...

What I found surprised me. The use of PID algorithms is now appearing in support of Micro-electro-mechanical systems (MEMS) in a new generation of motor control apps in the industrial automation, ...
