Book Description
The fundamental equation that describes limit cycles in nonlinear sampled-data systems was derived. The equivalence of limit cycles with finite pulsed systems having a periodically varying sampling-rate was observed, and the methods of analysis applied to the latter were extended to obtain these limit cycles with the aid of final value theorem. This fundamental equation is modified and simplified under certain assumptions as it can be applied to systems both with and without integrators. The limitation on the longest period of saturated and unsaturated oscillation is investigated and the critical gain for their existence is derived, starting from the modified fundamental equation. Also, the stability of limit cycles and the equilibrium point is considered, based on Neace's method. Various kinds of non-linearities, namely, pulse-width modulation, relay saturating amplifier with linear zone and quantized level amplifier are discussed. Self-excited oscillations are mainly examined, as well as the possible existence and stability of limit cycles, however, the method can be extended to forced oscillations.

Book Description
This book provides an approach to a basic stability analysis of the Pulse Width Modulated (PWM) Control Systems. It provides a systematic way to a general system solution of such and similar problems. The method described provides the designer with the ability to select system components and predict the system behavior. As a descriptive vehicle, it uses a simple system consisting of a pulse width modulator (PWM) and a linear system section W(s) to connect time and frequency domain via the Laplace transform. After the individual components are studied independently, it proceeds to analyze the system when the feedback loop is closed. The analysis is devoted mostly to symmetrical Pulse Width Modulators; however the Unsymmetrical Modulators are covered as well. The book gives the reader a broader approach to the study of such systems, providing detailed analytical tools for simple and more complex system control configuration. Near the end of the book, a direction is presented for further study of the Frequency Pulse Width Modulated (FPWM) control systems.
