What is control engineering?
Control engineering is a multidisciplinary field that combines mathematics, physics, computer science, and electrical engineering. The main goal of control engineering is to design systems that can achieve desired outputs or behaviors by using feedback mechanisms. Feedback is a process where the output or state of a system is measured and compared with a desired value or reference, and then used to adjust the input or parameters of the system accordingly.
For example, consider a thermostat that controls the temperature of a room. The thermostat measures the current temperature of the room and compares it with a set point (the desired temperature). If the current temperature is lower than the set point, the thermostat sends a signal to turn on the heater. If the current temperature is higher than the set point, the thermostat sends a signal to turn off the heater. In this way, the thermostat regulates the temperature of the room by using feedback.
Why is control engineering important?
Control engineering is important because it enables us to design systems that can perform complex tasks efficiently, reliably, and safely. Control engineering can improve the performance, stability, robustness, and accuracy of systems by using feedback to compensate for disturbances, uncertainties, and errors. Control engineering can also optimize the energy consumption, cost, and environmental impact of systems by using feedback to adjust their operation according to changing conditions and requirements.
Some examples of applications that rely on control engineering are:
Robotics: Control engineering can help robots to move, manipulate objects, navigate environments, coordinate with other robots, and perform various tasks autonomously.
Aerospace: Control engineering can help aircrafts, rockets, satellites, and spacecrafts to fly, orbit, land, communicate, and perform missions safely and efficiently.
Industrial automation: Control engineering can help machines, processes, and factories to produce goods and services with high quality, speed, and flexibility.
Biomedical devices: Control engineering can help devices such as pacemakers, insulin pumps, artificial organs, prosthetics, and brain-computer interfaces to monitor and regulate vital functions and enhance human health and well-being.
What are the main topics covered in control engineering?
Control engineering covers a wide range of topics that can be broadly classified into two categories: classical control theory and modern control theory.
Classical control theory deals with systems that are linear (meaning that their output is proportional to their input) and time-invariant (meaning that their behavior does not change over time). Classical control theory uses techniques such as Laplace transforms, frequency-domain analysis (such as Bode plots), root-locus analysis (such as Routh's criterion), Nyquist plots (such as Nyquist stability criterion), state-space representation (such as state transition matrix), etc. Classical control theory can design controllers such as proportional-integral-derivative (PID) controllers (such as Ziegler-Nichols method), lead-lag compensators (such as root-locus method), etc.
Modern control theory deals with systems that are nonlinear (meaning that their output is not proportional to their input) or time-varying (meaning that their behavior changes over time). Modern control theory uses techniques such as linearization (such as Taylor series expansion), optimization (such as calculus of variations), stochastic processes (such as Markov chains), game theory (such as Nash equilibrium), etc. Modern control theory can design controllers such as optimal controllers (such as linear-quadratic regulator), adaptive controllers (such as model reference adaptive control), robust controllers (such as Hinfinity control), intelligent controllers (such as fuzzy logic or neural networks), etc.
