基于虚拟样机与二型模糊系统的机车粘着控制

为了抑制轮对空转，并使轮轨间的粘着处于极限状态，需要开发基于虚拟样机和现代控制理论的机车粘着控制技术。组建了包括电力机车多刚体动力学模型、电力牵引传动系统和控制系统的仿真平台。针对电力机车牵引系统的强非线性和不确定性，引入二型模糊逻辑以实现机车粘着控制。仿真结果表明，在该仿真平台上能够成功实现基于二型模糊系统的粘着控制，并且能够较好地抑制空转现象，实现优化粘着控制。

Adhesion Control of Locomotive Based on Virtual Prototype and Type-2 Fuzzy Logic System

In order to restrain wheel-set slipping on rail, put the adhesion between wheels and rail often in an ultimate state, the adhesion control technology of locomotive on the basis of the virtual prototype and modern control theory is needed to develop. A simulation platform was built, which includes the multi-rigid-body dynamics model for an electric locomotive, the electric traction drive system and control system. Aiming at the strong nonlinearity and uncertainties of the electric locomotive traction system, the type-2 fuzzy logic is introduced to realize the locomotive adhesion control. The simulation results show that with the proposed method, the wheels slipping can be preferably suppressed and the optimized adhesion control can be realized.
