INTRODUCTION Control of nonlinear system is an important task. The system consists of a mass attached to a spring and damper. An approximate equivalent linear system can be derived from a non-linear system or process plant modelled in Simulink using the linear analysis tool of the Simulink control design toolbox. Like MATLAB, Simulink can be used with both linear and nonlinear systems, which can be modeled in continuous time, sample time, or a hybrid of these. Coverage is limited to basic topics that should be familiar to a simulation practitioner. These control methods require simple to complex controllers. Linear Models • Model is a mathematical representations of a system – Models allow simulating the system – Models can be used for conceptual analysis – Models are never exact • Linear models – Have simple structure – Can be analyzed using powerful mathematical tools – Can be matched against real data using known procedures Jun 10, 2017 · PDF | Control systems theory is a wide area covering a range of artificial and physical phenomena. Discrete systems could be to provide easy access to matrix software developed by the LINPACK (linear system package) and EISPACK (Eigen system package) projects. Yang · Tae G. Readers can not only learn the control concepts and problem solving methods but also coding skills by following the a way to make a linearized system model that operate as a model reference for the nonlinear system and provides the best performance for the nonlinear system.
