Nonlinear Systems Course
Dive into nonlinear systems engineering with hands-on modelling of friction, backlash, saturation, and more for precise vertical positioning. Master linearisation techniques, stability analysis using Lyapunov methods, controller design including feedback and sliding modes, and simulation validation to achieve high-accuracy control in practical applications like robotics and automation.

What will I learn?
This course offers a practical guide to modelling and controlling vertical positioning stages, accounting for friction, backlash, dead zones, and saturation. Learners will create simplified nonlinear models, find equilibria and linearisations, develop robust controllers, assess stability and limit cycles, and confirm performance via simulations with real-world precision standards.
