Key Points Control method that acts before error grows large Responds to input conditions or disturbances in advance Often combined with feedback control for better performance Used in industrial automation, process control, and systems with known disturbances Definition Feedforward Control…
Key Points Alarm Management System is a software system for handling alarms and operator notification Used in operational and control contexts Prevents operators from being overwhelmed by too many or poorly designed alarms Used in industrial automation, control rooms, utilities,…
Key Points Uses proportional, integral, and derivative terms Common in industrial control Helps regulate process variables Requires tuning for stability and response One of the most common closed-loop control strategies Definition PID Controller is a feedback controller that uses proportional,…
Key Points Starts, runs, and stops individual batches Uses recipe or sequence-driven control Common in chemicals, food production, and pharmaceuticals Relies on sequencing, recipes, and status tracking Each batch is controlled as a defined unit Definition Batch Process Control is…
Key Points Timing requirement where occasional misses degrade quality rather than cause failure Defined for network or system use in operational and control contexts Used in media, interactive systems, and latency-sensitive control applications Tolerates occasional misses while maintaining acceptable service…
Key Points Provides supervisory monitoring and control of distributed assets Collects telemetry from field devices Transmits data over communications links to centralized control interfaces Supports operator commands and control actions Common in utilities, water systems, pipelines, manufacturing, and infrastructure operations…
Key Points Deterministic Control exhibits predictable timing and bounded response Requires strict execution cycles and synchronized communication Used in operational and control contexts where timing certainty is critical Operates at the OT system layer Primary impacts: performance optimization, operational automation,…
Key Points Time-series storage for operational and process history Continuously collects and stores operational data for later retrieval and analysis Used in industrial automation, control systems, utilities, and operations centers Supports understanding how industrial systems behaved and changed over time…
Key Points Control method without output feedback correction Applied in contexts where the process is predictable enough that fixed input is acceptable Used in simple automation, timed operations, and systems where feedback is unavailable or unnecessary Simpler than feedback control…
Key Points Maintains operation after faults instead of immediate shutdown May continue in degraded mode with reduced capability Common in safety-critical and control applications Depends on redundancy, fallback modes, and fault isolation Preferred or required in industrial systems and resilient…
