Embodiment

[0175] Using a non-fragile dissipation filtering method for a networked control system proposed by the present invention, when there is no external disturbance, that is, when w(k)=0, the networked filtering error system is mean square exponentially stable. When there is an external disturbance, the system is also mean square exponentially stable and has a certain anti-interference ability. The specific implementation method is as follows:

[0176] 1) Consider the following networked control system:

[0177]

[0178] y(k)=[1 -2 1]x(k)+0.9w(k)

[0179] z(k)=[-2 1 -2]x(k)

[0180] Consider the following given parameters

[0181]

[0182] h 4 = 1,E 4 =0.02,H 3 =[1 0 0 0 2],

[0183] Take here When there is a parameter perturbation F 1 (k)=F 2 (k)=F 3 (k)=F 4 When (k)=I, it is assumed that the system disturbance input w(k)=1 / k 2 , consider the dissipative filtering problem of the system when Q, S, R select different values, where H ∞ Filtering can be seen as ...

Abstract

The invention discloses a non-fragile dissipative filter method implemented by networked control systems. The non-fragile dissipative filter method includes building networked filter error system models under the condition that the availability of delay and packet loss of the networked control systems and perturbation of parameters of filters is taken into consideration; constructing Lyapunov functions; acquiring sufficient conditions for the availability of mean square exponential stability of networked filter error systems and non-fragile dissipative filters by the aid of Lyapunov stability theories and linear matrix inequality analysis processes; solving the parameters of the filters by the aid of Matlab LMI tool boxes; providing parameter matrixes (as shown in the specifications) of the non-fragile dissipative filters. The non-fragile dissipative filter method has the advantages that sensor-filter packet loss and delay conditions are taken into consideration, Bernoulli distribution requirements can be met by the probability of packet loss and delay, accordingly, the non-fragile dissipative filter method has practical significance and is applicable to general dissipative filter including H8 filter, and the conservative property of designs of non-fragile filters can be lowered.

Description

technical field [0001] The invention relates to a networked control system and dissipation filtering, in particular to a non-fragile dissipation filtering method of a networked control system with time delay and packet loss. Background technique [0002] The closed-loop control system formed through the communication network is called networked control system (networked control system, abbreviated as NCSs). NCSs has the advantages of convenient installation and maintenance, high flexibility and easy reconfiguration. However, the introduction of the communication network has led to the following problems in the system: 1) Network delay: When data is transmitted in the communication network due to network congestion or external interference, there is a problem of network delay in the networked control system; 2) Packet loss : In the process of data transmission, due to network congestion and resource competition, the problem of data packet loss will be caused. At the same tim...
