When Designing Control Systems, What is a Control Strategy?

Written by Robert Davis | Jul 27, 2023 12:52:37 PM
A Control System Strategy defines how the system will respond to maintain stability, optimize performance, or achieve other predefined objectives.   

All elements of control system design are aimed at achieving one goal: getting system output to behave in a certain manner regardless of disturbances. In the context of control system design, a control strategy refers to a set of rules, algorithms, or methods used to manipulate the behavior of a system to achieve desired objectives. During control system design, experienced engineers analyze the system's characteristics and requirements to select and design the most appropriate control strategy to achieve the desired outcomes. Ongoing advancements in control theory and technologies continue to expand the range and effectiveness of control strategies across all industries and applications.

What is a Control System? 

A control system is a set of components and processes that work together to manage, regulate, and control the behavior of a system. All control systems, such as a mechanical governor on an engine or a thermostat on an electrical heater, are designed to ensure that the system behaves in a desired manner by regulating its inputs, processes, and outputs. Control systems are widely used in engineering, physics, chemistry, and other fields where it is necessary to maintain stability and optimize performance of a system.

Control systems are found in equipment and devices we encounter everyday, including:

7 Control System Strategies to consider during the design process 

The main goal of a control system is to regulate or manage the output of a system, process, or device to maintain certain conditions or achieve specific performance criteria. Therefore, the choice of the control strategy depends on the complexity of the system, the required performance, and the specific control objectives. These strategies can be implemented through various control techniques, including: 

  1. Proportional-Integral-Derivative (PID) Control: A widely used control strategy that adjusts the output based on the proportional, integral, and derivative terms of the error between the desired setpoint and the actual output.

  2. Model Predictive Control (MPC): A sophisticated control strategy that uses a dynamic mathematical model of the system to predict future behavior and make control decisions accordingly.

  3. On-Off Control: A simple control strategy that switches the system between two states based on a threshold or setpoint.

  4. Fuzzy Logic Control: A control strategy that uses fuzzy sets and linguistic variables to represent and process imprecise information, suitable for systems with uncertain or non-linear behavior.

  5. State-Space Control: A control strategy that represents the system in the form of state variables and their dynamics, allowing for more advanced control approaches.

  6. Adaptive Control: A control strategy that continuously adjusts the control parameters based on the system's changing characteristics or operating conditions.

  7. Feedforward Control: A control strategy that compensates for known disturbances or external inputs before they affect the system output.
