Abstract:

<p>In this thesis a novel method for controlling a manipulator with arbitrary number of Degrees of freedom is proposed, the proposed method has the main advantages of two common controllers, the simplicity of PID controller and the robustness and accuracy of adaptive controller. The controller architecture is based on an Artificial Neural Network (ANN) and a PID controller.</p><p>The controller has the ability of solving inverse dynamics and inverse kinematics of robot with two separate Artificial Neural Networks. Since the ANN is learning the system parameters by itself the structure of contr

Abstract:

For a linear time-invariant (LTI) plant, a robust controller is often designed in order to maintain robust stability and performance of the system. In robust controller implementation, two problems might arise. First, it is interesting to know whether it is possible to simplify the controller and to what degree before its implementation while still maintaining system robust performance. The second concern arises in real-time applications where the controller may have to be retuned or redesigned several times after the initial implementation stage. In both problems, it is important to know how

This study aims at designing and implementing a single channel stand-alone Brain-Controlled Switch (BCS) device, which records the electroencephalography (EEG) signals from the scalp using electrodes, amplifies it, eliminates interferences (associated with the EEG signals) and processes the EEG signals to extract and decode temporal signal features to determine user’s intention of regulating an external switch. The design of our “brain-controlled switch” device is implemented using a bio-potential amplifier and a microcontroller. The bio-potential amplifier amplifies the EEG signals to a leve

Abstract:

In this thesis, high performance torque and speed control for a surface-mounted permanent magnet synchronous machine (PMSM) is designed, simulated and implemented. A three-phase two-level pulse width modulation voltage-source inverter (PWM-VSI) with power MOSFETs is used to feed the PMSM. The study has three objectives. The first is to compensate the voltage disturbance caused by nonideal characteristics of the voltage-source inverter (VSI). The second is to decouple the coupled variables in the synchronous reference frame model of the PMSM. The last is to design a load torque estimator in ord

Therefore, a bird’s wing has six degrees of motion, which requires a total of six motors to complete the imitation. To faithfully follow the path of a flapping wing, the six motors have to be controlled synchronously. This thesis aims to design a motor control system, which drives the ornithopter platform to tra

Abstract:

Since Fuzzy controllers are nonlinear, it is more difficult to set the controller gains compared to Proportional-Integral-Derivative (PID) controller. The idea is to start with a tuned conventional PID controller, replace it with an equivalent fuzzy controller. In contrast, a PID controller is a simple, linear combination of three signals: P action proportional to error, the I-action proportional to the integral of the error and the D-action proportional to the time derivative of error. This introduces a systematic tuning procedure for fuzzy PID type controllers and study of higher order syste

碩士<br>國立成功大學<br>造船及船舶機械工程學系<br>87<br>The performance of fuzzy logic controller can be improved though the following methods: the structure of controller , the tuning of parameters and the regulating of control rules。 The last one is the most effective among them。Rules self-regulating fuzzy controller is one of those being able to modify fuzzy automatically。Now we prefer a algorithm to realize the technique of self-organized fuzzy controller to adjust change of error gain。It can control close loop system freely arrive steady state time。The self-organized fuzzy controller is assist controller to
