Digital clock using GUI : The MATLAB software includes a timer object that can be used to schedule the execution of MATLAB commands. We’ll see how to create timer objects, start a timer running, and

Introduction Lyapunov stability is often used to describe the state of being stable in a dynamical system. An equilibrium state x* of a dynamical system is Lyapunov stable if all trajectories of the system starting from

Phase Portrait A phase portrait is a geometric representation of the trajectories of a dynamic system in the phase plane. Every curve or point represents a set of initial conditions. Phase portraits are an

Introduction The describing function analysis is an approximate technique for studying non-linear systems. The basic idea of the method is to approximate the non-linear systems. The basic idea is of the method is to

Introduction A control system is a system of devices or set of devices, that manages, commands, directs or regulates the behavior of other device(s) or system(s) to achieve desire results. As the human civilization

What is a non-linearity? By definition, non- linear systems are those that do not follow the principle of superposition and homogeneity. Simply speaking, change in input is not proportional to the change in output.

Introduction Steady-state error is defined as the difference between the input (command) and the output of a system in the limit as time goes to infinity (i.e. when the response has reached steady state).

Introduction The Routh-Hurwitz stability criterion provides a simple algorithm to decide whether or not the zeros of a polynomial are all in the left half of the complex plane (such a polynomial is called
