The equation, with a negative definite, yields a unique positive definite solution if and only if the eigenvalues of are in the closed left half-plane: A stable system: The definite integral is the solution to if is asymptotically stable. In the theory of ordinary differential equations (ODEs), Lyapunov functions are scalar functions that may be used to prove the stability of an equilibrium of an ODE. Named after the Russian mathematician Aleksandr Mikhailovich Lyapunov, Lyapunov functions (also called the Lyapunov’s second method for stability) are important to stability theory of dynamical systems and control theory.

This section describes the available solvers that can be selected by the ‘method’ parameter. The default method is direct if M is less than 10 and bilinear otherwise.. Method direct uses a direct analytical solution to the discrete Lyapunov equation. The algorithm is given in, for example,.However it requires the linear solution of a system with dimension \(M^2\) so that.

The book is the first book on complex matrix equations including the conjugate of unknown matrices. The study of these conjugate matrix equations is motivated by the investigations on stabilization and model reference tracking control for discrete-time antilinear systems, which are a particular. Lyapunov theory is used to make conclusions about trajectories of a system x˙ = f(x) (e.g., G.A.S.) without ﬁnding the trajectories (i.e., solving the diﬀerential equation) a typical Lyapunov theorem has the form: • if there exists a function V: Rn → R that satisﬁes some conditions on V and V˙ • then, trajectories of system satisfy some property if.

The study of these conjugate matrix equations is motivated by the investigations on stabilization and model reference tracking control for discrete-time antilinear systems, which are a particular kind of complex system with structure constraints.

We can use this version of the Lyapunov equation to define a condition for stability in discrete-time systems: Lyapunov Stability Theorem (Digital Systems) A digital system with the system matrix A is asymptotically stable if and only if there exists a unique matrix M that satisfies the Lyapunov Equation for every positive definite matrix N.

The Lyapunov Matrix Equation in System Stability and Control covers mathematical developments and applications while providing quick and easy references for solutions to engineering and mathematical problems. Lyapunov’s stability analysis technique is very common and dominant. The main deficiency, which severely limits its utilization, in reality, is the complication linked with the development of the Lyapunov function which is needed by the technique.
