fixed point or periodic solution. Stability of unstable fixed point and unstable periodic solution in the
controlled system is determined by the Routh 2 Hurwitz criterion and Melnikov’s method in generalized
Hamiltonian systems’theory , respectively. Numerical simulation results in Lorenz and Rossler sys 2

Description: In this chapter, we shall deal with the stabilization problem for singular systems.
The purpose is the design of controllers such that the closed-loop system
is regular, stable and impulse-free (in the continuous case) or causal (in the discrete
case). For continuous singular systems, both state feedback and dynamic
output feedback controllers are considered. Based on the stability conditions
presented in Chapter 2, the stabilizing controller design can be formulated
as a convex optimization problem characterized by linear matrix inequalities
(LMI). In the context of discrete singular systems, a necessary and sufficient
condition for the existence of stabilizing state feedback controllers is obtained. Platform: |

Description: By analyzing the mathematical model of the
three-phase pulse width modulation (PWM) current-source
rectifier (CSR) in a stationary reference frame based on the
instantaneous power theory, a voltage-oriented CSR power
control strategy was proposed. As an alternative approach for
active damping, the proportional capacitor-voltage feedback
was used to damp the inductor-capacitor filter (LC) resonance.
The system transfer function of the inner-current loop was
analyzed using the frequency response method. In order to
improve the limitations on dynamic response and stability of

Description: In control theory and stability theory, root locus analysis a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system. This is a technique used as a stability criterion in the field of classical control theory developed by Walter R. Evans which can determine stability of the system. The root locus plots the poles of the closed loop transfer function in the complex s-plane as a function of a gain parameter.-In control theory and stability theory, root locus analysis is a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system.
