Description
Technical field：
The invention belongs to mechanical engineering control field, more particularly to a kind of frequency domain performance of designed phase anticipatory control link
Curve map method.
Background technology：
As controlled mechanical system control performance (stability, accuracy and rapidity) be unsatisfactory for require, then can by
The method for increasing correction link in system, to improve the control performance of controlled mechanical system.Phase anticipatory control is conventional school
One of correction method.
In mechanical engineering control field, the most commonly used method of designed phase anticipatory control link is to be carried out using Bode diagram
The Frequency Domain Design Method of design.The method is general with phase margin as performance indications, is determined by analytical Calculation by Bode diagram
Correction link parameter.The method meets given phase margin requirement, is feasible solution, but be not optimal solution.In addition, to system control
The frequency domain performance indications of performance evaluation processed are not only phase margin, also shearing frequency, cut-off frequency, resonance peak, amplitude
Nargin etc.；Need checking computations other performance index whether also to meet on the basis of Preliminary design to require, be such as unsatisfactory for, it is necessary to repeatedly
Design repeatedly and check, be to cumbersome and time-consuming until meeting all properties index request.
It is conflicting because the performance to control system has between many requirements, multiple Control performance standards；Correction
Influence of the link parameter to system control performance is also conflicting.Therefore, the parameter designing of correction link be one very
Important and extremely difficult problem.
The content of the invention：
The present invention is directed to deficiency of the prior art, proposes a kind of frequency domain performance curve of designed phase anticipatory control link
Figure method, its have intuitively, system and it is comprehensive the characteristics of.
The present invention solves the scheme that is used of its technical problem：A kind of frequency domain performance of designed phase anticipatory control link
Curve map method, coordinate in length and breadth is respectively with two control parameters of phase anticipatory control link, sets up a two dimension ginseng for bounded
Number design space.With frequency domain Control performance standard as object function, two control parameters with phase anticipatory control link are to set
Meter variable, draws the isopleth of each Control performance standard in parameter designing space, can obtain the control performance curve of system
Figure.Control performance curve map presents the one-to-one relationship between Control performance standard and correction link parameter.Coordinate and right
Than each performance chart, then the comprehensively optimal correction link parameter of control performance is can obtain, complete the optimal of correction link
Change design.
Brief description of the drawings：
Fig. 1 is ssystem transfer function block diagram.
Fig. 2 is resonance peak performance chart.
Fig. 3 is cut-off frequency performance chart.
Fig. 4 is phase margin performance chart.
Fig. 5 is shearing frequency performance chart.
Fig. 6 is unit step response curve figure.
Specific embodiment：
Below in conjunction with drawings and Examples, the invention will be further described：
It is as shown in Figure 1 ssystem transfer function block diagram, wherein Kb=40 is the amplification coefficient of system amplifier, and phase surpasses
The transmission function of preceding correction link isIt has two control parameters, respectively T and α, and has 0.05≤α ＜ 1, this
In our available parameter T span be 0 ＜ T ＜ 1.
It is respectively coordinate in length and breadth with the control parameter T and α of bounded, then can obtains the parameter designing space of correction link.With frequency
Domain Control performance standard is object function, with parameter T and α as design variable, object function etc. is drawn in parameter designing space
Value line, then can obtain the performance chart of each performance indications.
Fig. 2 show resonance peak performance chart, Fig. 3 and show cut-off frequency performance chart, Fig. 4 and show phase
Nargin performance chart, Fig. 5 show shearing frequency performance chart.Coordinate and contrast each performance chart, then can obtain
The optimal correction link parameter of combination property.For example, the parameter that correction link may be selected here is T=0.1 and α=0.1.
Fig. 6 show the unit-step nsponse curve figure of system, and three subgraphs correspond to correction link respectively in described Fig. 6
The unit-step nsponse curve of system when parameter is T=0 and α=0 (without correction link)；Correction link parameter is T=0.0514
With α=0.233 (to meet phase margin more than or equal to 45 °, using the school that the frequency domain response method for designing based on Bode diagram is obtained
Positive link parameter) when system unit-step nsponse curve；Correction link parameter is T=0.1 and the frequency domain (is applied in α=0.1
The correction link parameter that performance chart method is obtained) when system unit-step nsponse curve.Three subgraphs can shown in comparison diagram 6
See, frequency domain performance chart method can significantly improve the control performance of system, and with directly perceived, system, it is comprehensive the characteristics of.
