Specific embodiment
It should be noted that in the case where not conflicting, the embodiment and the feature in embodiment in the present invention can phase
Mutually combination.
Below with reference to the accompanying drawings and in conjunction with the embodiments describing the present invention in detail.
The adjustment control method of variable-area turbocharger jet blade position, as shown in figure 1, using three closed loops
Control, respectively position ring, speed ring and electric current loop,
The target position information of the jet blade that the input of the position ring sends including Engine ECU and detect
The actual position information of jet blade, it is inclined with the position of actual position information that the position ring obtains first target position information
Difference, then the position deviation value is provided into target velocity (size and Orientation) by position control computing；

It is milder, overshoot will not be produced.
The positional control algorithm of the position ring of the present invention, will not produce overshoot, and its input is position deviation, according to " deviation-
Target velocity " curve, obtains target velocity；" deviation-target velocity " be by the Test Summary of early stage out, in little deviation
When, target velocity is less, it is also possible to be set to zero, and leaf position can be with constant when implying that permission little deviation；In large deviation, if
Put the maximum target speed of permission, plus fast-response；In middle differential location, can be according to linear between maximal rate and minimum speed
Table look-up determination.
Due to realizing that the turbine and worm changement that leaf position is adjusted has mechanical position limitation, in order to prevent mechanical punching
Hit, the target velocity for obtaining of tabling look-up is needed through once limiting, and carries out Redundancy Design, it is ensured that the electric machine theory near mechanical position limitation
Rotating speed is zero.As shown in figure 3, due to frame for movement limited location, in order to prevent mechanical shock, increase the service life, in place
Limited target maximal rate in the algorithm of the position control computing for putting ring.When near mechanical position limitation, reduce the big of target velocity
It is little, make motor toward mechanical position limitation operate when, speed slowly declines, and during to restraining position, speed is zero, it is to avoid impact.
The speeds control computing of the speed ring uses PI control algolithms, the current control computing of the electric current loop use than
Example control algolithm, still response speed can be accelerated droop control.
The inventive method is the computing of above-mentioned position ring, speed ring and the electric current loop realized by nozzle ring position controller
Processing procedure, nozzle ring position controller can receive the target position information of the jet blade that Engine ECU sends, and most
DC signal is exported eventually, and direct current generator receives this DC signal, realizes rotating；Described turbine and worm changement one end
It is connected with the output of motor, one end is connected with the control-rod of jet blade, the forward and reverse rotation motion of motor is converted to into control
The straight reciprocating motion of bar processed, realizes the position control of jet blade.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
