The Nonlinear Control Applications course aims to study nonlinear systems and their applications in mathematical and non-mathematical fields. Understanding the concept of nonlinear control focuses on, among other things, linearization around the equilibrium point, nonlinear systems with or without loops, relocation of pole positions, systems with a state feedback or output feedback, several types of feedback (proportional, integral, derivative, and PID), as well as application of optimal control principles to the optimal solution of a nonlinear problem. The discussion also discusses system properties based on system response and pole position to assess stability, controllability and observability with or without feedback. Application and simulation are discussed with illustrations of techno-echo-entrepreneur-maths based problems. Learning is carried out by applying a combination of problem-based learning approaches, discussions and conventional methods. Learning activities are directed at motivating skills in group presentations on specified topics. The implementation of the assessment is determined by proportional weighting, which is carried out during the learning process with active interactive participation, presentations, assignments and mid-semester exams, as well as final semester exams.
