Comparison between single neuron PI adjustment and normal PI adjustment has been performed. The LIM used in the serve system is threephase Yconnected twopole kW 50 Hz 380 V type. The parameters of LIM are: Rs= Ω, Rr= Ω, Ls= H, Lm= H, Lr= H, τ= m. presents simulation result by LIM model discussed above. 18 shows the parison of speed tracking with normal PI unit and single neuron work PI unit. From the simulation, it can be concluded that the speed response of the single neuron work PI adjustment is fast, and the steadystate error is step response, the speed fluctuation is small. In this paper, an equation circuit considering the dynamic end effect of LIM is discussed, which is suitable for the large end effect condition. The model for vector control has been presented. Single neuron work PI unit is introduced for LIM servodrive. The simulative conclusion shows that the end effect can be pensated by this model, and the control system performance is improved. The single neuron work PI unit is suitable for the control arithmetic design. 19 V: Set up speed。 ATR: Torque regulator。 Boldea and Nasar, 1999). When the vector control strategy is applied to LIM, the influence of the end effect must be considered and an exact mathematical model should be constituted to improve the whole performance of the control system. In this paper, the equation circuit of LIM considering large end effect is discussed, and the calculation model of LIM is deduced. The intelligent control method is adopted to solve the problem of robustness. The single neuron control PI unit is adopted for LIM servodrive because of its simple configuration. The simulation has validated the obvious effects of those 12 methods on improving the whole performance, including reliability.
