: This paper describes a new tool developed for the design of nonlinear controllers based on the well known input-output and input-state linearizing techniques. NLSoft is several symbolic manipulation modules, which employ certain differential geometric tools for the design and simulation of control systems. NLSOFT is developed with a user-friendly graphical user interface (GUI). In order to facilitate the real-time implementation, a new and powerful module permitting the calculation time of linearizing control laws considering several Digital Signal Processors (DSPs) characteristics is integrated in this new tool. NLSoft is validated considering two examples.
