This paper develops the ideas of speed and flux sensorless sliding mode control of PM synchronous machine. A sliding mode observer / controller is proposed in this paper. The convergence of the nonlinear time varying observer along with the asymptotic stability of the controller is analyzed. Pulse width modulation implementation using sliding mode concepts is also discussed. The major attention...

A novel methodology to create a powerful controller for robots that minimises the design effort is presented. We show that using the feedback from the robot itself, the system can learn from experience. A method is presented where the interpretation of the sensory feedback is integrated in the creation of the controller, which is achieved by growing a spiking neural network system. The feedback...

In this paper, we present the BladeAxe: an iPad-based musical instrument leveraging the concepts of “augmented mobile device” and “hybrid physical model controller.” By being almost fully standalone, it can be used easily on stage in the frame of a live performance by simply plugging it to a traditional guitar amplifier or to any sound system. Its acoustical plucking system provides the perform...

This paper presents the development of an embedded motion controller for a voice-coil driven linear motion stage. The linear motion module is integrated with a voice coil actuator, a linear guidance system, and a linear encoder. The controller is based on a TI TMS320LF2407A DSP board. It performs the servo motion control by providing motion profile generation, position determination, position e...

An MIMO auto-tuning method is develop that can be used by a layman of control. The method is based on MIMO identification and robust control design. The identification part delivers process model and model error bounds. The controller design block performs control synthesis, simulation and robust analysis. All steps can be done automatically. The parameters the user needs to enter are minimal a...

This paper deals with a design problem of an observer-based robust preview control system for uncertain discrete-time systems. In this approach, we adopt 2-stage design scheme and we derive an observer-based robust controller with integral and preview actions such that a given performance index is satisfactorily small for uncertainties. In this paper, we show that suÆcient conditions for the ex...

In this paper, the stability analysis and controller design for uncertain discretetime singularly perturbed system are investigated via a matrix inequality approach. In analysis, the stability condition under which the singularly perturbed system is quadratically stable for sufficiently small singular perturbation parameter is derived in the formulation of linear matrix inequality (LMI). In syn...

The use of soft-computing algorithms in hardware-in-the-loop applications has been investigated. A Proportional-Integral-Derivative (PID) classical controller and a Fuzzy Logic Controller (FLC) were designed and successfully tested on the Turbine Technologies SR-30 turbojet engine for the main-stage operation of the engine. Transfer function model of the plant was obtained using frequency-respo...

The design of reduced-order controllers under specific performance and structure requirements is dealt in this contribution. Two controllers are designed and compared. The first one was designed using H∞ theory whereas the latter one is designed departing from a parametric-optimization via a two-stage algorithm. The time spent by the designer using our second approach is largely reduced. An act...

Because of extreme local saturation at pole tips of excited phase and uncircular shape of rotor and stator, a Swithed Reluctance Motor (SRM) does not have a simple and accurate mathematical model. Therefore, the output control of this motor requires a robust controller which is not based on an accurate model of the process. Fuzzy controllers, to some extent, will satisfy these requirements. Tet...
