Design and control of automotive propulsion systems

"This publication offers analytical and experimental tools and achievements in designing mechanical and mechatronic driveline platforms. Examples comprise numerous strength dividing devices, together with symmetric and non-symmetric types, in addition to open and lockable differentials, a variety of constrained slip differentials, no spins, and viscous clutches.

Specifically, constraining the rate at which the dynamics of the switching function A(t) can evolve on the equilibrium manifold, it is possible to address input rate saturation constraints. 24) that a constraint on the rate at which the dynamics of the parameter A(t) can evolve on the equilibrium manifold can be enforced effectively placing a rate constraint on the control u(t). 4, we present an algorithm that outlines the key steps in constructing the hierarchical switching feedback controller.

4a. If no solution exists, )~s(x(t)) is unchanged. 4b. If one solution ~1 exists and p(~l) < p(,~) then switch )~s(x(t)) to )~1. 4c. ). Note that multiple solutions can be avoided by modifying the ca 's. Step 5. 11) holds. ) such that Step 3 is satisfied, can be guaranteed by modifying the first part Step 4 as follows: Step 4'. , search for the solutions of V~(x(tk)) < c~, )~ 9 As. In this case, the switching set S C_ As need not be explicitly defined and is computed online. Furthermore, the case where AT ~ 0 recovers the continuous framework described in this section.

34), ~ x x x=Xs(x) = q(z)vxscz)(z)' it follows that ~'(x) - dp(A)dA As(x) = q(x)vxs(x)~s(x). 41) is immediate. 33). 5. 43) where c : De --~ R l• is an arbitrary row vector such that c(x)vT(x) # O, x E De, A E S. 33).
