Finding equilibrium points
WebIf at least one has a positive real part, the point is unstable. If at least one eigenvalue has negative real part and at least one has positive real part, the equilibrium is a saddle point and it is unstable. If all the eigenvalues are real and have the same sign the point is called a node. See also. Autonomous equation; Critical point; Steady ... Web0 is a stable equilibrium point. • If a strict Lyapunov function exists, then x 0 is an asymptotically stable equilibrium point. • (LaSalle) If a Lyapunov function V exists, and for every initial point y = x 0 the function t →V (φ(t,y)) is not a constant, then x 0 is an asymptotically stable equilibrium point.

Finding equilibrium points of a continuous-time model d x d t = G ( x) can be done in the same way as for a discrete-time model, … WebTo find the critical points of a two variable function, find the partial derivatives of the function with respect to x and y. Then, set the partial derivatives equal to zero and solve the system of equations to find the critical points. Use the second partial derivative test in order to classify these points as maxima, minima or saddle points.
