Adaptive Control of Brushless DC Motors without Model Reduction
Authors: Kai Chen Yu, , Huang An Chyau
Published: March 2013

Various applications of brushless DC motors (BLDCM) can be found in the industrial environment. However, almost all controllers designed for BLDCM are based on reduced models where a first order dynamics is regarded as the internal model. This way a second order dynamics is considered with considerable simplification in the controller design. Since the reduced model may not reflect the entire dynamics of the motor, some deterioration in the control outcome can be observed. To improve the performance, this paper considers the adaptive control of a BLDCM without using reduced model. Some unknown time-varying payloads are applied to ensure its effectiveness in practical applications. Rigorous mathematics proof of closed loop stability is provided together with the boundedness of the internal parameters. Simulation cases are given to show efficacy of the proposed scheme.

Published: March 2013

In this paper, the organic hybrids materials consisting of polarized polymers and small molecules were prepared and the morphology properties were studied by SEM. For CPE/BPSR (60/40) hybrid, the BPSR crystals existed primarily as micro-sized particles, and the particles size distribution was large. The CPE/ZKF (60/40) hybrid was almost in the amorphous state and there was only a small amount of crystallites dispersed in the amorphous phase. Though the interfacial interaction between BPSR particles and CPE matrix was poor, one of the interesting phenomena was observed, when a small amount of BPSR was incorporated into CPE/ZKF hybrid. The domain size of BPSR was dramatically decreased and existed as nano-particles in the CPE/ZKF/BPSR composites. In the case of CPE/ZKF/BPSR composites, the three-dimensional hydrogen-bonding networks could compress and aggregate the molecularly dispersed BPSR into nano-scaled particles.

Since both groups of materials are with the same mass ratio of coarse aggregates, the heterogeneity of the gravels distribution in concrete with larger grain size is higher than the other. The results show that the group with smaller aggregate grain size gains higher material fracture strength and fracture energy than another group. Then the concrete with more homogeneous meso-structure will reach higher fracture properties

In the paper, a novel 2-DOF (degree of freedom) plane translational parallel manipulator with passive universal joints and three legs is presented. Firstly, the 2-DOF translational parallel manipulator which has the spatial structure and high bearing capacity in the direction perpendicular to the kinematics plane is described. Then, the kinematics analysis of the 2-DOF parallel manipulator, which include inverse and forward solutions, are studied in detail, and the Jacobian matrix of the parallel manipulator is also derived based on it. Lastly, to improve the stability and bearing capacity further, the symmetric mechanisms with four legs and passive universal joints are constructed by adding a leg in parallel. The proposed 2-DOF parallel manipulator not only has the simple structure, but high stiffness especially in the direction perpendicular to kinematics plane for its spatial arrangment and passive universal joints.

With the deep analysis on the rotational speed measurement and the error existed in the measurement process at present, this paper introduces a high precision rotational speed measurement system based on infrared sensor and microcontroller. This system combines with improved measuring method. The sensor is an infrared photoelectric sensor, and uses its characteristics of the autocollimator ensured accuracy of measurement. The photoelectric sensor outputs weak voltage pulse signal when it receives the reflected infrared light. And then the signal is processed by double-reversed amplification and twice pulse shaping circuit. The system uses the relevant logic functions of a D-type flip-flop to control two 16-bit microcontroller chip timing/counter turned on and off simultaneously, and calculates the rotation speed. At last, the result is displayed on LED by Microcontroller. This measurement system has high accuracy, fast sampling speed and wide measuring range.

Published: March 2013

To solve the problem of speckle noise, CCD photoelectric noise and background light noise in non-diffracting beam triangulation and improve measurement accuracy and resolution, we use gray dynamic filtering theory. In the non-diffraction beam triangulation measurement system, the measured signal is reconstructed at the maximum peak of the spots by implementing the dynamic GM genetic filtering methods based on the grey system theory. There are only four main steps of modeling. The first step is to update the system dynamically and continuously. The second step is to effectively obtain low frequency trend component,The third step is solving the problem of the low rate of complex multi-measurement.The last is solve the problem of the limit of unsuitable online measurement. This method of triangulation measurement based on the non-diffracting beam have higher measurement accuracy and higher resolution over the traditional laser triangulation measurement system.
