This paper considers implementation and test of a self-tuning PI-controller based on pole-placement. The algorithm has been implemented in BASIC on an ABC-80. The sampling of measure values and setting of digital outputs has been done with a remote station TA6500.
The controller has been tested on two processes. First on a test process where the temperature from a hairdryer has been contr
This work is meant to make it probable that, without direct measurement in the fuel line, it is possible to calculate the fuel flow with other parameters.
The investigation is made in one specific case, for a four cylinder carburetor engine. With the model parameters engine speed and intake manifold pressure it is possible to construct a model which showed a good agreement in a comparison wit
Logger is an interactive command driven program for data logging on PDP-ll. It can also generate different signals, perform PID-control and make signal processing. During the logging it is possible to plot or print signals on the terminal. Commands can be entered via the terminal or in a command fi1e. For conversion of the stored signals to text form the program Convrt can be used.
This paper deals with automatic steering of ships under the influence of disturbances from waves. The disturbance has been of two different types, a sinusoidal wave and a disturbance in the yaw rate. We have used both conventional state feedback regulators and adaptive regulators based on least square estimation and minimum variance control. In particular, we have investigated the behaviour of the
