Example 1.1 A very simple RLC network shown in Figure 1.1 is considered.
Suppose that the voltage u(t) is the input to the RLC network. This circuit contains two energy-storage elements: the inductor and the capacitor. Applying Kirchhoff's laws, the voltage uc (t) across the capacitor C and the current iL (t) through the inductor L satisfv the following diifferential equations.
The second-order differential equation (1. 4) is called the differential equation description of the system.The differential equation description can be directly converted to the transfer function description by Laplace transform. By taking the Laplace transform of (1.4) and assuming the zero initial conditions hold true, the transfer function description of the RLC network is obtained asFrom the description (1.4) and (1.5), it can be seen that the differential equation description and the transfer function description are all the external descriptions of a system.
If we make the definitions,x1(t) = uc(t) and X2 (t) =iL (t), for t∈(0,t], the following differential equations can be obtained from (1.1) and (1.2).
The set of the differential equations in matrix form (1.8) or(1.9)is called the state equation of the system.
The set of the algebraic equations in the matrix form (1.11) is called the output equation of the system.
Both the state equation and the output equation are called the state space description of asystem. The state space description is an internal description of system.
Lyapunov asymptotically stability means that we are able to select a bound on initial condition, that will result in the state trajectory which remains within a chosen finite limit and will return to Xe. The geometrical implication of Lyapunov asymptotically stability is shown in Figure 3. 2.
Definition 3.9 If δ, which is appear in (3.19) and indicates the bound on initial condition, is not the function of to and the equilibrium point Xe is stable i. s. L, then Xe is said to be uniformly stable.
Definition 3.10 If δ, which is appear in (3.19) and indicates the bound on initial condition, is not the function of to and the equilibrium point Xe iS asymptotically stable i. s. L, then Xe iS said to be ruuformly asymptotically stable.
Definition 3.11 If the equilibrium point Xe iS asymptotically stable i. s. L for any initial state, then the equilibrium point Xe iS said to be globally asymptotically stable or asymptotically stable in the large.
