Infinite-horizon model predictive control with structured input signals

American control Conference (ACC)

Model predictive control (MPC) is a very popular controller design method in the process industry. One of the main advantages of MPC is that it can handle constraints on the inputs and outputs and it is capable of tracking pre-scheduled reference signals. In the paper the infinite prediction horizon problem is discussed. The input signal has been structured, in order to be able to handle signal constraints, to track pre-scheduled reference signals and to reject measurable disturbances. Beyond a switching horizon, the input signal is described by a number of (orthogonal) basis functions or a static state feedback. By structuring the input, the degrees of freedom in the resulting optimization problem remains bounded. The optimal infinite-horizon model predictive control-law is given in a closed form. In the unconstrained case an expression for the LTI controller is derived.

Nonlinear separation control method was constructed for a STEC (spring thermal energy conversion) pilot plant. The nonlinear separation control consists of nonlinear statics compensation and linear dynamics compensation. In this paper, evaporator outlet heat quantity of working fluid was controlled by use of the nonlinear separation method.

In this paper, subspace-based algorithms for the simultaneous identification of the linear and nonlinear parts of multivariable Hammerstein and Wiener models are presented. The proposed algorithms consist basically of two steps. The first one is a standard (linear) subspace algorithm applied to an equivalent linear system whose inputs (respectively outputs) are filtered (by the nonlinear functions describing the static nonlinearities) versions of the original inputs (respectively outputs). The second step consists in a 2-norm minimization problem which is solved via a Singular Value Decomposition. Copyright © 2002 IFAC.

Energy-optimal gait analysis of quadruped robots

Artificial Life and Robotics 2002年第3期6卷 120-125页

作者： Kiguchi, Kazuo Kusumoto, Yukihiro Watanabe, Keigo Izumi, Kiyotaka Fukuda, Toshio Department of Advanced Systems Control Engineering Graduate School of Science and Engineering Saga University Saga Japan Interior Design Research Institute Fukuoka Indistrial Technology Center Fukuoka Japan Department of Micro System Engineering Graduate School of Engineering Nagoya University Nagoya Japan

It is important for walking robots such as quadruped robots to have an efficient gait. Since animals and insects are the basic models for most walking robots, their walking patterns are good examples. In this study, the walking energy consumption of a quadruped robot is analyzed and compared with natural animal gaits. Genetic algorithms have been applied to obtain the energy-optimal gait when the quadruped robot is walking with a set velocity. In this method, an individual in a population represents the walking pattern of the quadruped robot. The gait (individual) which consumes the least energy is considered to be the best gait (individual) in this study. The energy-optimal gait is analyzed at several walking velocities, since the amount of walking energy consumption changes if the walking velocity of the robot is changed. The results of this study can be used to decide what type of gait should be generated for a quadruped robot as its walking velocity changes.

In this paper, agent-based architecture has been introduced into GIS for interactability and scalability. We have developed an interface agent to interactively assist the user with the query formation process. The interface agent has a capability of offering domain knowledge that is associated with a given query. Also the agent records users troubleshooting experience and show them to the same user and other user as hints. Further, we also have developed the agent-based architecture with a 2-tier mediator model in GIS to meet the needs for interoperability among diverse application domains and integration of heterogeneous information source. Also broker agent provides a matchmaking service to other agent. As a result, qualitative and quantitative data can be integrated into GIS. Also we describe a prototype system, GXGIS, using agent-based technology.

This paper is concerned with the argument that the identification of Takagi Sugeno (T-S) fuzzy models from training data should involve an important feature between data fitness and model complexity. One hand a (T-S) fuzzy model with a large number of fuzzy rules may encounter the risk of having an approximation capable of fitting training data well. On the other hand it may be difficult to run this fuzzy model structure due to heavy computational cost. In order to facilitate the development of a balance between these requirements, a Higher Order Singular Value Decomposition (HOSVD) based T-S fuzzy model reduction is introduced using the well-known Yam SVD fuzzy rule-based approximation technique. © 2001 EUCA.

An electromagnetic-type vibratory feeder of is a typical transportation device used in automatic weighers. As existing feeders are driven by feedforward control, the so-called "firing angle control", the driver cannot negate sudden disturbances. In this study, we consider applying a feedback control for such a feeder system. First, we give the two details of modelings for the vibration part and for the electromagnetic force part. Next, a feedback control system is constructed for the electromagnetic vibration feeder for which we propose a two-degrees-of-freedom proportional plus integral plus derivative (PID) controller with nonlinear elements. Next, we apply the feedback control to the feeder with a standard trough. Finally, we consider a method compatible with many varieties of troughs by adjusting a nonlinear element. On the basis of the results of some experiments, we confirm that the two-degrees-of-freedom PID control is more effective than the conventional firing angle control.

The emitter turn-off thyristor (ETO) is a new MOS-controlled thyristor that is suitable for use in high-power converters due to its improved switching performance and easy control. This paper analyzes the abnormal failures related to the parasitic diode of the ETO in high-frequency converters for the first time. To prevent this failure, several solutions are proposed and improved ETOs are developed. Experimental results show that the proposed solutions can properly solve this problem.
