The Nonlinear Synthesis Tools software package provides a set of functions for synthesizing controllers for nonlinear systems within the MATLAB® environment. These functions simplify the process of controller design for nonlinear dynamic systems.

The software package contains functions for the following nonlinear control design methods:

• Feedback linearization, with or without time-scale separation, followed by:
  • Robust pole placement
  • Linear quadratic control
  • Sliding mode control
• State-dependent Riccati equation based control
• Recursive back-stepping control
• Predictive control
• Quickest-descent control

These approaches and their variants provide a total of 9 different techniques for nonlinear control system synthesis.
