Another purpose of the present invention provides the device of implementing said method.
For achieving the above object, technical scheme of the present invention is as follows:
Control method of the present invention, be that multidestination, multichannel, multiple source system are reduced X, Y, Z tri-consult volume system respectively, in tri-consult volume, stay of two nights X and information source Z are the amounts of knowing that can choose arbitrarily according to system state, channel Y is subjected to the control of system start-up parameter S and control variable C and determines that can it by gating, but each strobe channel is subjected to system's control and realizes gating at random, channel status parameter Yi is handled as random parameter by system, the mathematical model of random processing is complete group random state equation, and is as follows:
Wherein: i=1,2 ..., n
N is the number of channel, and Yi is the state parameter of channel i,
Si is the start-up control parameter of system to channel i,
Cik is K the control variable of system to channel i, and the K value is big more, and the control right of priority of Cik is big more, and Cik can comprise system's input control variable and STATE FEEDBACK CONTROL variable, and W is the control variable number, and " " is self-defining OZH operational symbol, and it is defined as:
Wherein when Cik for must allow control command the time, get (a) formula computing in the following formula,
Cik in the time of must forbidding control command, gets (b) formula computing in the following formula.

As stated above, operational plan pre-deposits in the computing machine according to system with stay of two nights X and information source Z parameter, and can revise at any time, then when computing machine accesses one group of X and Z parameter, correspondingly determine strobe channel Y parameter randomly by said method, handle the total system operational plan in this way, thereby realize that multidestination, multichannel, multiple source system automatically command control according to schedule.
Theoretical foundation of the present invention is as follows:
1, the notion of complete group:
For limited Discrete Stochastic incident A1, A2 ..., An, if A1, A2 ..., An mutual exclusion, and A1UA2U ... UAn=Ω, A1 then, A2 ..., An constitutes the exhaustive events group, and the probability of happening of above-mentioned incident satisfies;
O≤P(Ai)≤1
P (Ω)=1, P (φ)=0 can release again: A1=A2UA3U ... UAn (1-1)
A2＝ A1UA3U…UAn (1-2)
Ai＝ A1UA2U…UA1－1UAi＋1…UAn (1-i)
An＝ A1UA2…UAn－1 (1-n)
Above-mentioned A1, A2 ... relational expression between the An promptly constitutes basic complete group random state equation, and they show, as complete group A1, A2,, Ai ... there is a certain incident Ai to take place among the An randomly, then the incident of other except that Ai is just inevitable does not take place, the A1 on the equation left side, A2 ... An is random state output.The equilibrium condition of equation is: certain unique in and if only if complete group incident Ai takes place, and its complementary event does not take place simultaneously for true.But this balance is temporary transient, at random, implicit unbalanced factor in the balance, and the source one of this unbalanced factor is to be input control parameter, this is the controllable characteristics of complete group; The 2nd, be the system state feedback parameters, this is the adaptive characteristic of complete group.
Introduce OZA function δ D, that is:
Then above-mentioned (1-i) formula is abbreviated as:
2, mathematical model and analysis thereof
For multidestination, multichannel, multiple source system, the present invention carries out analysis and Control to channel Y parameter, requirement to channel is: the one, and each channel is equal to, the 2nd, channel of each connection, in case certain channel breaks down, is fully loaded with, special plane takies or analogue takes place, then this channel withdraws from the control of complete group mathematical model, and promptly control device is no longer considered this channel when the control of gating at random.
For channel Y parameter, its basic complete group random state equation is:
(1) introduce start-up control variable Si when system, Si can change among both at Ω, φ, then:
When Si=φ, Yi=φ shows that channel i is closed or stops;
When Si=Ω, channel i is in initial random duty, can enable.
When Si became Ω by φ, equation (8) formula all had unique Yi output, and is Y1, Y2 ..., any one is at random among the Yn.
After introducing self-defining BZA operational symbol " ", but promptly constitute the STOCHASTIC CONTROL state equation of analysis and Control variable C, i.e. (A) formula.
For example: four control variable Ci1 are arranged, Ci2, Ci3, Ci4, they are respectively: must allow, must forbid, must forbid and must allow, then:
3, the present invention comprises the basic purpose of multidestination, multichannel, the control of multiple source system implementation: (1) any one information source or a plurality of information source arrive any one stay of two nights or any a plurality of stay of two nights by any one Channel Processing; (2) all stays of two nights can divide into groups to obtain the same combination information source of combination in any in needed same information source or a plurality of information source arbitrarily; (3) any channel can be finished the work separately, also can be used as the alternate channel of its complete any channel; (4) all channels can combination in any and carrying row; (5) all channels can be removed renewal arbitrarily; (6) any stay of two nights can be changed required information source at any time.
For example Y1 need remove renewal, and then Y1 withdraws from complete group, produces new complete group again, and generation Y1 removes complete subgroup random state equation:
In like manner can produce the complete subgroup of Y1 parallel operation random state equation, the complete subgroup of Y1 special plane random state equation etc.
The instruction of control system is divided into two classes, first stochastic instruction, it two is status commands, status command is the system state feedback controling variable, generally can include and carry instruction, special plane instruction etc., have the instruction of carrying to be called the detachment machine instruction again, the special plane instruction is called inevitable work order again, and fully loaded instruction comprises the instructions that state sent such as machine is fully loaded, fault, overload, dismounting maintenance.These instructions belong to the instruction of not working or no longer accepting work and requiring other machine to help.Work such as when this instruction is 1, then corresponding channel breaks away from the complete group STOCHASTIC CONTROL, finishes the task of system by other channel, and this channel carries out parallel operation, change, this control procedure is finished automatically.
Control method of the present invention, can with the dirigibility of system from fixing limited rise to unlimited at random, reliability with system, be transformed to state in parallel by series connection, thereby make the microcosmic fault of system, macroscopic view does not show, and certain channel breaks down it is deactivated automatically, is finished the task of system by other channel.The present invention makes the reliability amount of the reaching height of system, and systemic-function reaches arbitrarily flexibly.
