Judicious Introduction

I really like how you emphasize the "judicious introduction" of time delays. I have seen some folks use time delays as a quick fix without carefully evaluating their effect on the entire system, which can either be a great solution or it can introduce other errors in subtle ways.

I have been involved in developing, improving and consulting anything related with control system for the last 15 years in electronics component testing and automation system. Time delay is really important and at some cases it is the only mean to solve the problems.

add delay = conserve phase

When the control loop is some derivative of a PID loop, maintaining phase is very good advice.

When there are unavoidable delays present in the system, your suggestion of some kind of "wait and act" strategy is probably good advice.  When you think about it, adding a delay in the control loop is just another way to "conserve phase".

What if algae borne of fertilizer runoff that pollutes rivers and lakes could be harvested and used as biofuel feedstock? What if the leftovers could be recycled into farm soil nutrients, eliminating at least some of the need for artificial fertilizers in the first place? Western Michigan University researchers have a plan.

Manufacturers of plastic parts recognize the potential of conformal cooling to reduce molding cycle times. Problem is, conformal molds require additive manufacturing (AM), and technologies in that space are still evolving. Costs also can be high, and beyond that, many manufacturing organizations lack the knowledge and expertise needed to apply and incorporate additive technologies into their operations.
