Description
Technical field
The present invention relates to a kind of emulation test system for aeroengine control system, relate in particular to a kind of for aeromotor digital electronic controller hardware the emulation test system in loop.
Background technology
Current, aeroengine control system be a multivariate, time become, non-linear, multi-functional complex digital formula control system, the quality of its performance directly affects the performance of aeromotor and aircraft, it is also a highly difficult technology simultaneously, wants the work such as completion system development, ground stand test run, HIGHER ALTITUDE TEST FACILITY test run and installation Flight therebetween.Along with controlling the increase of functional requirement and being on the increase of control variable, control system becomes increasingly complex, and wherein, the input/output signal type of digital electronic controller becomes tens kinds from several; Number of signals becomes up to a hundred individual from tens, even hundreds of; It is also more and more higher that precision is controlled requirement.Complicated signal parameter brought very large difficulty to the development of engine and control system and test and later maintenance, and artificial these supplemental characteristics of acquisition and processing have brought cost significantly to increase and the prolongation of time.In order to reduce controlling system design cost, shorten the lead time, reduce development risk, guarantee the safety in engine test process, must be by a large amount of engine l-G simulation test and fault simulation before engine enters actual test run, fully grasp after the characteristic of control system, guarantee instructs engineering practice effect in engine run, prevents unexpected generation.So must consider very important " pair " product one engine simulator (revertive control device) in design and development control system, in order to substitute real engine, carry out a large amount of control system functional verification experiments.In < < aeromotor Digital electronic control system general specification > > newly revised edition for the emulation overlay capacity requirement of CNC system hardware loop fault and engine failure (single and combined fault), complexity depending on engine and control system function can reach geometric series, depend merely on manually and cannot complete huge test job amount, so must take corresponding measure in the development of emulator.
At present domesticly carry out the technological means that electronic controller dependence test takes and have in several ways:
A kind of is development specialized simulation electronic controller monitor station, adopt tradition with the experimental technique means of manual operation simulation electronic instrument and equipment, can carry out open-loop test to controller individual feature, but because automaticity is low, functions of the equipments are single, operating process is complicated, test efficiency is low, for complicated engine simulation object, need to carry out the closed loop test occasion of control system combination function, if hardware is at loop-around test, just helpless.
Another kind is the external professional emulation test system product of buying, as the HIL based on ADvantage FrameWork (hardware is in the loop) emulation test system of U.S. ADI company, what adopt is based on pci bus architecture system, system product forms complicated, board mostly adopts traditional golden finger pattern, its shortcoming is mainly that structural reliability is not high enough, heat dispersion is bad, can not meet mobile and antivibration requirement, for be the emulation testing of laboratory condition, for needing the provisional test occasion in outfield to be not suitable for, simultaneously due to technical protection reason, it adopts special-purpose real time operating system, system lacks versatility, compatibility hardware support kit producer is few, cause high system input cost, and higher later stage operation expense, make its cost performance not high.Crucial core technology, as opaque to user in engine mathematical model, once simulation object changes, must drop into again the substantial contribution exploitation of again signing an agreement.
Also having a kind of is to put in airplane complete machine system synthesis l-G simulation test to go to examine, testing table as described in 200910147119.0 < < airplane engine dynamic simulation test bed > > patent, this testing table for be the analogue simulation of the practical work process of engine complex control system in whole flight envelope, be mainly that the harmony of controlling function with power system is controlled in checking flight, and be not for the engine characteristics emulation in controlling system design process.Its weak point is: this test bench installation forms huge, can only meet the test under laboratory environment condition; Although this testing table also includes engine simulation equipment, but because specific aim is not strong, on system, model emulation computing machine does not adopt hardware real-time system, completely by software timing, cannot meet control system for the requirement of the upper accurate timing of control law checking, likely can cause in type of project repeatedly; On engine sensor simulated behavior, still adopt nonstandard device collocation analog or digital circuit interface, its platform versatility is not strong, due to different controller electric interfaces matching problems, may cause the uncertain of test findings; On fault simulation, this testing table does not possess simulation hardware loop fault, as signal open circuit, short circuit, noise etc.
