The loop-shaping method, a method that utilizes the weighting function based on the H/sub /spl infin// control theory, is applied in the design of the stabilization compensator. The entire control system has been designed according to the concept of the two-degrees-of-freedom system. We herein report the results of computer simulation of a control system using the thus designed compensator, as well as the experimental results of a control system which uses a gyroscope to detect the attitude. The results of our experiments indicate that we have been successful in tumbler stabilization control.","PeriodicalId":344374,"journal":{"name":"SICE '95.

In the experiments, 11 subjects added force or impact to the robot and evaluated its reaction by the rating scale method.

As the results, the emotions being flexible, pleasant, and human-like were explained by a linear regression model of the impedance values and classified into 4 groups from the view point of the contact force and response speed.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The main problems in force control are overshoot overdamping and unknown environment (e.g. the stiffness of object). So, the main idea is to use dynamic compensation for a known robotic plant and fuzzy compensation is introduced here for an unknown environment to improve the system performance. The fuzzy compensation is implemented by using a rule based fuzzy approach to identified the unknown environment.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The authors focus their attention on the feedback property achieved at the plant output side. First, the authors give an explicit representation of the sensitivity matrix obtained by enforcing the conventional LTR procedure. In addition, the authors discuss an application of the partial LTR technique which has been proposed for lumped non-minimum phase plants. The authors show that a feedback property recovered by enforcing the conventional LTR procedure can be recovered by the partial LTR technique. A simple numerical example is presented to illustrate the feedback properties achieved by the LTR techniques.","PeriodicalId":344374,"journal":{"name":"SICE '95.

As a result, we show that the n-th moments of the Riggs and Phillips approximations (1987) converge to those of the solution of Ito equation, which is in contrast to the case of the standard Runge Kutta method. Therefore we must convert the white noise differential equations into the equivalent Ito equations before we use the Riggs and Phillips method for digital simulation. An improved version of the Riggs and Phillips method is also presented.","PeriodicalId":344374,"journal":{"name":"SICE '95. Proceedings of the 34th SICE Annual Conference.

Usually this factorization is done numerically. For that, the computational complexity is cubic in the degrees of freedom (DOF) of the system at hand. In this paper, a symbolic factorization of the inertia matrix is presented. This allows one to calculate the joint accelerations with the complexity that is linear in the DOF. The approach is originally introduced for the simulation of fixed-base industrial manipulators. Here, the method is extended to serial type space robots.","PeriodicalId":344374,"journal":{"name":"SICE '95. Proceedings of the 34th SICE Annual Conference.

In a thermal power plant the temperature between the hot steam and the cold rotor causes the thermal stress. The excess thermal stresses shorten the life span of the steam turbine rotor and restrict the start up time of the plant. The control algorithm designed by a model predictive control method calculates the optimal future profile of the steam flow rate at every control interval. The actual steam flow rate is controlled to the optimal profile which enables start up of the turbine in the shortest period keeping the thermal stress under the allowable value. Numerical examples show the effectiveness of the algorithm.","PeriodicalId":344374,"journal":{"name":"SICE '95. Proceedings of the 34th SICE Annual Conference.
