Example: Double-well potential V(x) = x2 2 + x4 4 The paths in the phase plane are contours of constant H(x) = p2 2 x2 2 + x4 4 = E:. I There are lots of practical systems which can be approximated by second-order systems, and apply phase plane analysis. December 24, 1991. This is also translated as a phase shift, from the free running frequency. 1a) x&2 = f2(x1,x2) (2. Second order systems (3 classes). Due to the existence of grid impedance and other reactive elements, resonance and harmonic distortion is easy to appear in AC system, which is different from DC system. The main. In the phase plane, equation σ=0 represents a line, called sliding line, passing through the origin (Which is the final equilibrium point for the system). For these models, global analysis is performed by using specific low dimensional tools (phase plane methods, Poincaré-Bendixson theorem, etc. In nonlinear cases, inwardly propagating waves were re-vealed ﬁrst in the objects of spiral waves also target waves called as antispirals 5,7. Quite generally, these systems demonstrate a phase transition as the coupling between the oscillators is strengthened, leading to the emergence of a self-organized synchronized state.
