∟Phase Space and Phase Portrait
This chapter provides an introduction of phase space and phase portrait. Topics include introduction of canonical coordinates of a system; trajectory curves of a system for a given period of time; phase portraits of free fall, simple harmonic, and pendulum motions; motion equations of linear systems; 2-D homogeneous linear systems.
What Is Phase Space
What Is Phase Portrait
Phase Portrait of Simple Harmonic Motion
Phase Portrait of Pendulum Motion
Motion Equations of Linear Systems
Phase Portraits of 2-D Homogeneous Linear Systems
Takeaways:
- Phase Space is the collection of all possible sets of canonical coordinates
of a system.
- Canonical Coordinates are generalized position components, qi,
extended with generalized momentum components pi.
- Phase Portrait is the trajectory curve of
a system in the the Phase Space for a given period of time.
- Motion equations in a linear system are
first order linear differential equations of the canonical coordinates.
- 2-D homogeneous linear systems
can be classified based on characteristic polynomials of their coefficient matrixes.
