Embodiment 1
[0066] Such as Figure 4 As shown, in a control system composed of n (n≥2) trains, train 1 (T-1) is the first train, train 2 (T-2) is the second train, and train n (T-n) is the last train. l 1 , l 2 ,...,l n are the lengths of T-1, T-2,..., T-n respectively. are respectively the positions of the tails of the kT cycle start times T-1, T-2,..., T-n. are the speeds of trains T-1, T-2,..., T-n at the beginning of the kT period, respectively. Respectively, the distances from the tail position of the kT cycle start time T-2, T-3, T-n train to the rear of the front train,
[0067] In the CBTC system, the train and ZC are strictly time-synchronized, and the sampling period of the train state is very short. Therefore, the three-train control system can be regarded as a discrete linear time-invariant system. Using the method of state space, the multi-train control system is expressed as:

Embodiment 2
[0144] like Figure 5 As shown, the control system consists of 3 trains, train 1 (T-1) is the first train, train 2 (T-2) is the middle train, and train 3 (T-3) is the tail train. l 1 , l 2 , l 3 They are the lengths of T-1, T-2, and T-3 respectively. Respectively, the position of the tail of the kT cycle start time T-1, T-2, T-3. They are the speeds of T-1, T-2, T-3 at the beginning of the kT period, respectively. is the distance from the tail of T-2 to the tail of T-1, is the distance from the tail of T-3 to the tail of T-2,
[0145] In the CBTC system, the train and ZC time are strictly synchronized, and the sampling period T of the train state is very short. The three-train control system can be regarded as a discrete linear non-time-varying system. Using the method of state space, the three-train control system is expressed as:
[0146] x k+1 =AX k +BU k ,
[0147] u k =-GX k ,
[0148] Among them, X k is the state matrix of three trains; U k is th...
