Control systems engineering is the discipline of designing feedback loops that drive dynamic systems toward desired behavior. From cruise control in your car to the autopilot on an aircraft, feedback controllers measure output, compare it to a reference, and compute corrective inputs — a cycle that repeats thousands of times per second.
These simulations let you tune PID controllers in real time, analyze frequency response via Bode plots, trace root locus paths as gain varies, explore state-space representations, and evaluate stability with Nyquist diagrams — all with interactive, animated visualizations grounded in classical and modern control theory.
