Thus, information is ne.de. on the.role.of stre.m se.ime.ts in re.ulating transie.t phosphorus (P) to be.te. unde.stand the.re.ationship be.we.n nutrie.t inputs and wate. quality.

Powe.train Fue. Consumption Mode.ing and Be.chmark Analysis of a Paralle. P4 Hybrid e.e.tric Ve.icle.Using Dynamic Programming

Journal of Transportation Te.hnologie. 2022年第4期12卷 804-832页

The.goal of this work is to de.e.op a hybrid e.e.tric ve.icle.mode. that is suitable.for use.in a dynamic programming algorithm that provide. the.be.chmark for optimal control of the.hybrid powe.train. The.be.chmark analysis e.ploys dynamic programming by backward induction to de.e.mine.the.globally optimal solution by solving the.e.e.gy manage.e.t proble. starting at the.final time.te. and proce.ding backwards in time. This me.hod re.uire. the.de.e.opme.t of a backwards facing mode. that propagate. the.whe.l spe.d of the.ve.icle.for the.give. drive.cycle.through the.drive.ine.compone.ts to de.e.mine.the.ope.ating points of the.powe.train. Although dynamic programming only se.rche. the.solution space.within the.fe.sible.re.ions of ope.ation, the.be.chmarking mode. must be.solve. for e.e.y admissible.state.at e.e.y time.te. le.ding to strict re.uire.e.ts for runtime.and me.ory. The.backward facing mode. e.ploys the.quasi-static assumption of powe.train ope.ation to re.uce.the.fide.ity of the.mode. to accommodate.the.e.re.uire.e.ts. Ve.ification and validation te.ting of the.dynamic programming algorithm is conducte. to e.sure.succe.sful ope.ation of the.algorithm and to asse.s the.validity of the.de.e.mine. control policy against a high-fide.ity forward-facing ve.icle.mode. with a pe.ce.t diffe.e.ce.of fue. consumption of 1.2%. The.be.chmark analysis is conducte. ove. multiple.drive.cycle. to de.e.mine.the.optimal control policy that provide. a be.chmark for re.l-time.algorithm de.e.opme.t and de.e.mine. control tre.ds that can be.use. to improve.e.isting algorithms.
