【正文】 eat order. So for structure. The haleness that controls the integral whole to turn turns sex Research of design, have the important meaning. For long time, the structure and controls parts all be the lone mold piece to establish Account of, the structure has been turn design excellently after, add the superior control system to the structure again Up. The result that cause thus is that can39。t consider two systems to match, making the system The parameter is mutually interference, design the possible result of the result of badly. So have the necessity Gather structure and controls the empress carries on again the design. Cultural heritage [21] discussed the structure and control of gather design, design of objects on having the structure of the active control, control to exert in the damping of shut the wreath system three On the number. This problem was defined to many targets excellent turn , fasten with the structure weight and control The energy of the is the target function, changing with an area the conduct and actions design of the structure piece Quantity. Many targets are excellent to turn the problem a little bit difficult to lie in almost nonexistent solution39。s make all The target function attains at the same time superior. So used and can go the superior solution in the text all Read aloud. Solve many targets excellent turn the problem general of is use add the power factor each target line Sex bines a target, but will cause solution of beg is not necessarily whole thus Superior solution in bureau. It adopted the method of the theory in the text to solve, use the related power value To handle the relation between many targets, carried on an analysis at the same time, knot with the assurance Strong sex of the fruit. Cultural heritage[ structural haleness that 22] pares to discussed to have thoroughly to control actively Design the problem, point out that the gentle structure speaks from the essence to is to distribute the parameter system. Limit In a calculation of look like the processing and will cause the error margin of the parameter, and will cause the mold of Lose. Also exist the equal indetermination in the structure parameter, these indetermination Will affect the stability and the function characteristic of control the system clearly. Therefore must be indeed Settle the parameter moves the influence to the system function. The stick of the feedback control system bee For an important problem within design. Need to consider two kinds of sticks in design process Sex: The stability stick and the function stick. Before to the research 第 頁(yè) 共 61 頁(yè) 13 of the stability stick mainly in the area of the convenient single value resolve To plete, but then use an analysis to the research of the function stick at the area enter Go. At the same time in design process the research stability stick and the function stick of The cultural heritage less. Cultural heritage[22] considers these two kinds of stick at the same time, using to shut the wreath system especially Advertise for the appearance number of be worth the matrix to reflect the stability stick, with the related and intelligent degree Mean the function stick. In the text for making the system attain the haleness superior, adopt many The target is excellent to turn, the target function contain 4: (1) The stability stick。 (2) Function Stick。 (3) Structure weight。 (4) Control the system energy. The adoption is in conjunction with the misty strategy Learning to solve problem can go the superior solution. 5 be over languages (1) According to the strong sex design of the quantity engineering, can call it as broad sense Of strong sex design method, is mainly in the design to the machine structure in the manufacturing The deviation of produce takes in to overe, the ability that make product have resist to make the error margin interference Dint. Method of provide mostly with experiment to design technique is basal, and consider Of all is the static state problem, take no account of the product in work process oneself of function. Now The empress mainly works to lie in put forward more effectively of strong design method. ( 2) According to an analytical and strong sex design, can call it as Righteousness of strong sex design method, mainly is to excellent turn hereafter of as a result carry on the cent , Make it have the haleness. Apply the noodles more narrow. (3) Currently structure. The strong sex research that controls the integral whole to turn is only in consideration of Gather control the stick of the system behind, but did not do for the haleness of the structure parameter Study, so gather the system haleness of empress is a new and worthy lesson (4) The concept of the haleness originates the control( the stick), the empress leads to go into gradually The quantity engineering, have already permeated toward mechanical engineering now. The strong sex design of the machine system is One course that door is brandnew, it will to design the huge influence of renewal creation of method. Is under the condition of current each course permeates each other, mutual plement particularly, mechanical Haleness and structure. Control the integral whole to turn the strong design is this realm of front follow the lesson . How build up the evaluation index sign of the haleness, is an important foundation research。 How The haleness of the in the control stick and the machine structure anically the knot put together, It is the point place of the theories also will rise to the extensive application of the intelligence structure Arrive the very big propulsion function. 第 頁(yè) 共 61 頁(yè) 14
