In our laboratory, various design control engineering is important. In our laboratory, various design technique which guaranteed the stability of control systems for the technique which guaranteed the stability of control systems for the nonlinear and time delay systems. Concrete contents are as nonlinear and time delay systems. Concrete contents are as follows.follows.1. The nonlinear controlled object is expressed by fuzzy modeling, 1. The nonlinear controlled object is expressed by fuzzy and the control law which asymptotically agrees with the stable modeling, and the control law which asymptotically agrees with the stable model followed by the output is constituted.model followed by the output is constituted. The condition as the whole control systems is stable is The condition as the whole control systems is stable is clarified, and clarified, and responsibility and stability are confirmed in the responsibility and stability are confirmed in the numerical examples.numerical examples.2. For the systems including the delay times, the model 2. For the systems including the delay times, the model following following type control law is constituted using operator type control law is constituted using operator vectors and state vectors and state estimation, and the condition for becoming estimation, and the condition for becoming that the whole control that the whole control systems is stabilized is deduced. Responsibility and stability are confirmed in the numerical systems is stabilized is deduced. Responsibility and stability are examples.confirmed in the numerical examples.3. The practical uses of above 1 and 2 control methods are 3. The practical uses of above 1 and 2 control methods are attempted.Appealing Point:Special objectivesTaking advantage of the research technique and result relevant to system control engineering, the automation and energy saving in the Taking advantage of the research technique and result industrial world are aimed at.relevant to system control engineering, the automation and energy saving in the industrial world are aimed at.attempted.Mechanics, Soft MatterSystems-Control Engineering, Biomechanics, Solid MechanicsAdditive Manufacturing for Polymer GelsSoft & Wet MatterEngineering Lab.ＰＰｌｌａａｎｎｔｔ（（ＮＮｏｏｎｎｌｌｉｉｎｎｅｅａａｒｒＳＳｙｙｓｓｔｔｅｅｍｍｓｓ））ＲＲｅｅｆｆｅｅｒｒｅｅｎｎｃｃｅｅＭＭｏｏｄｄｅｅｌｌScanning Microscopic Light ScatteringHigh StrengthLow FrictionConsortium/Research Inst.(SMILS)Content：Content【【Research Outline】】【Research Outline】We aim to implement soft matter in society.
