The present work aims to expand the possibilities of PD 3 control strategies implementation and to evaluate, in a practical way, different strategies of fuzzy logic application in the control of processes of a didactic plant (PD 3). This was accomplished by adding fuzzy control strategies to the conventional industrial control strategies with which the PD 3 system is factory configured. The conventional strategies use PID controllers and its variations (P, PI and PD) which parameters are preset and "implanted" in the instruments. Three fuzzy control strategies were performed with temperature a

Abstract:

Nos últimos anos, tem havido grande interesse em estudar manipuladores paralelos, aplicados principalmente em simuladores de voo, com seis graus de liberdade. O interesse em estruturas cinemáticas paralelas é motivado por sua alta rigidez e excelente capacidade de posicionamento em relação às estruturas cinemáticas seriais. Além disso, como os atuadores são posicionados em uma base, eles podem ser aplicados em cargas pesadas e ainda apresentam baixo consumo de energia, tendo em vista que vários atuadores atuam simultaneamente no mesmo corpo.

碩士<br>國立成功大學<br>造船及船舶機械工程學系<br>87<br>This paper presents a fuzzy self-tuning PID control scheme for NAME''s flap-type wavemaker driven by the electrohydraulic cylinder. The essential idea of the scheme is to parameterize a Ziegler-Nichols-like tuning formula based on relay control by a single parameter. With process output error and error rate as inputs, use an on-line fuzzy inference mechanism to achieve a real-time self-tuning controller. According to simulated analysis and experimental results, the performance of the scheme improve considerably and is better then pure PID control.

Abstract:

碩士<br>國立成功大學<br>化學工程研究所<br>85<br>An adaptive fuzzy PID controller is developed based on the fuzzy inference system which adjusts adaptively the PID parameters and precompensates for the process output error. The fuzzy inference system built on a PID controller initiated with available tuning methods inherits the desirable robustness of conventional PID controllers. An extensive study for a wide variety of process dynamic demonstrates the superiority of the proposed fuzzy PID controller. The adaptive fuzzy scheme does not require information a priori except for the design of the fuzzy inf

Fuzzy controller is a knowledge-based system that translates the experts experiences into fuzzy linguistic terms. This knowledge base is used as an inference mechanism.

However, it must have some limitation when we control the different object. To deal with nonlinear system and time-invariant system may exist some difficulties and the parameter is not so easy to be adjust. Therefore, those specialists begin researching how to combine the conventional PID and the other control theory for having better efficiency of control and self-adjustment to achieve the parament of

The positioning accuracy and transient performance of the piezoelectric actuator are often deteriorated due to the nonlinear hysteresis phenomenon.

Therefore, the steady-state error will exist in the system performance. In this research, a PID-like fuzzy controller is developed based on three parameters, i.e., the system error, error change and the acceleration of system error. The viewpoints of kinematics ar

The respective scaling factors of both the Fuzzy PI and PD controllers are adjusted by the fuzzy inference rules. Therefore, four sets of fuzzy rules are to be designed
