FeatureSolutions for Unstable Industrial Processes
Negative resistance also known as positive feedback can cause processes to jump, accelerate and oscillate confusing the control system and the operator. -
FeatureAutoQuiz: How to Choose Best Method for Level Measurement
Radar does not depend on temperature or composition of a fluid as long as the beam is narrow and the dielectric constant of the fluid is greater than two. -
FeatureAutoQuiz: Loop Tuning Terminology for Change in Amplitude
The common method of judging tuning is known as the "quarter wave decay" method. It has been shown if a loop is tuned so the oscillation decays with each wave being one quarter of the previous wave, i -
FeatureAutoQuiz: How to Simultaneously Optimize an Interacting Dead-Time Dominant Process with Multiple Constraints
Model predictive control excels at dead-time dominance and simultaneous optimization while accounting for future prediction of proximity to constraints. -
FeatureAutoQuiz: Which Flowmeter Type Does Not Operate on the Principle That a Differential Pressure Is Developed Across a Flow Restriction?
