As it is well known I-PD controllers are widely used for process control, because they have good performance. However, it is very difficult to determine I-PD gains in case of controlled object with deadtime. Here, we propose a self-tuning I-PD controller and show the simulation and experimental results to demonstrate the effectiveness of our method.","PeriodicalId":344374,"journal":{"name":"SICE '95.

It is shown that when the time-varying Fourier coefficients are in the random-walk motion, the quasi-periodic signal is represented by the stochastic state model whose state noise reflects the random increment of the Fourier coefficients. The state-space optimal FIR filter can then be applied to the state model to get the optimal short-time estimate. For the signals whose Fourier coefficients are nearly constant in the short-time interval, a simplified solution of the optimal FIR filter is also suggested. It is shown that the optimal FIR filter in the harmonic analysis problem is a stochastic and structural generalization of the DFT, and the optimal FIR filter gives exact harmonic estimate when the signal is periodic and noiseless. It is also shown by examples that the noise suppressing and the ability to resolve changes of the Fourier coefficients can be tuned by adjusting the filter length and the noise covariance setting.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The control objective in this paper is steam temperature control of the boiler for power generation at the start-up stage, which is regarded as one of the most difficult ones among power plant controls because of strong process nonlinearity and dependence on the start-up conditions. In the paper, the concept of the simulator-model-based system identification and control method is introduced briefly. Then the proposed method is explained in detail through its application procedure to the plant model, which is regarded as an actual plant. Finally, some results of simulation studies are shown to demonstrate the effectiveness of the proposed method.","PeriodicalId":344374,"journal":{"name":"SICE '95.

We combine online planning for a desired signal and control system design. The planner is part of the control system. The planned desired signal is changed with the state of the servo system. Online planning has an advantage over traditional off-line planning in that the planning as well as the servo system reduces the influence of disturbance, parameter perturbation and initial value. Preview control can't be utilized for online planning because the future desired signal depends on the future and present state of the control system, but the proposed method uses the future restriction of the desired signal. By integration of preview planning and online planning, the planner can prevent the output of the controlled object from spilling over the permitted domain better than without preview planning. Online planning constructs a feedback loop and preview planning adds feedforward. The domain within which the 3-wheeled vehicle moves is usually restricted by various obstacles etc. It can be regarded as the restriction of the desired signal. Information of the obstacle within a certain distance can be given by the sensor. Online planner can use the information of the future restriction in advance. The vehicle can start to avoid the obstacle earlier than without preview planning. We show a simulation result.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The system was comprised of systemic circulation, pulmonary circulation, arterial and venous circulation. Cardiovascular system was shown to be stable but uncontrollable. The singular values decreased rapidly at physiological frequency range while it showed positive values at low frequency. The amplitude and the duration of oscillation of the impulse responses and the singular values with optimized feedback control were markedly smaller than those without it. Thus in the autonomous state of cardiovascular system, adequate control of venous return is the most critical point to achieve optimal circulatory state.

For such a problem, a simple method is presented whereby some sufficient conditions are derived so that discrete-time systems remain stable in the presence of norm-bounded time-varying uncertain perturbations. Some analytic method and a discrete type of Bellman-Gronwall inequality are employed to investigate such robust stability conditions. Moreover, in the light of such robust stability conditions, we can select the parameters of a dynamical controller so that uncertain discrete-time systems are stable, which lead to a controller design procedure. Finally, a numerical example is given to demonstrate the validity of results.","PeriodicalId":344374,"journal":{"name":"SICE '95. Proceedings of the 34th SICE Annual Conference.

This CACSD system provides a large freedom in the choice of controller structure and in the design specifications. Effectiveness of the proposed CACSD system is illustrated by a design example where the multiobjective optimization by GA is compared with a goal attainment method in MATLAB OPTIMIZATION TOOLBOX.","PeriodicalId":344374,"journal":{"name":"SICE '95.
