International Conference on Issues and Challenges in Intelligent Computing Techniques (ICICT)

作者： Richa Sharma K.P.S Rana Vineet Kumar Instrumentation and Control Engineering Division Netaji Sub has Institute of Technology Delhi India

The robotic manipulators have extensively been used in many industry like manufacturing, assembly etc., space and medical applications for the purpose of pick and place, positioning and path following etc. This requires accurate control of an end-effector of robotic manipulators as these are Multi-Input Multi-Output (MIMO), nonlinear and coupled systems. Being complex in nature tuning of the controllers is a critical issue and have been an area of research in the control community. In this paper, Genetic Algorithm (GA) is used for optimization of gains of the two Proportional-Integral-Derivative (PID) controllers applied to each link of a two-link planar rigid robotic manipulator. Performance indices namely Integral Square of Error (ISE) and Integral Square of Change in controller Output (ISCCO) with equal weightage for both the links are considered for optimization. As GA is a global search technique, normally there are several solutions available in a given search space for same performance indices. The PID controllers used in the said two-link planar rigid robotic manipulator were optimized 2000 times and a statistical analysis is carried out on the obtained optimal gains and fitness function values to estimate the diversity of optimized solutions. The motivation behind this simulation study has been to provide an overall knowledge to the user for choosing the appropriate controller gains yielding suitable controller signals which should be preferred for system design specifications and cost effective hardware implementation of robotic manipulators while maintaining the desired tracking performance.

In this paper speed control of a Hybrid Electric Vehicle (HEV) is presented. The HEV is operated in parallel configuration. The HEV is driven by an Internal Combustion Engine (ICE) and a Permanent Magnet Synchronous Motor (PMSM) drive. The PMSM is driven by a battery and a Photovoltaic (PV) module. In this paper the performance of the vehicle in conventional (driven by ICE only) and hybrid modes is compared. In this paper the performance of a PV module and its use to assist the battery to drive PMSM drive are also investigated.

In this paper, a novel fractional fuzzy proportional-integral-derivative controller (FFPID) is proposed. The proposed controller combines the effect of fractional-order PID (FOPID) control with fuzzy logic control (FLC) to obtain a robust and effective controller. All the five parameters are first tuned using Genetic Algorithm. Fine tuning of the integer-order parameters is then done using Fuzzy logic controller. Combining these two techniques, results in a new controller called fractional fuzzy PID controller. The effectiveness and robustness of the new methodology is illustrated by applying the proposed controller on two fractional order systems; viz control of a fractional-order-system and a fractional-order plant with dead time. It is observed that the performance of the proposed controller provides better control as compared to that of PID and FOPID controllers.

International Journal of Automation and computing 2013年第2期10卷 91-98页

作者： Vineet Kumar A. P. Mittal R. Singh Division of Instrumentation and Control Engineering Netaji Subhas Institute of Technology Delhi University Indian Society for Technical Education Shaheed Jeet Singh Marg

The study presented in this paper is in continuation with the paper published by the authors on parallel fuzzy proportional plus fuzzy integral plus fuzzy derivative （FP ＋ FI ＋ FD） controller. It addresses the stability analysis of parallel FP ＋ FI ＋ FD controller. The famous＂small gain theorem＂ is used to study the bounded-input and bounded-output （BIBO） stability of the fuzzy controller. Sufficient BIBO-stability conditions are developed for parallel FP ＋ FI ＋ FD controller. FP ＋ FI ＋ FD controller is derived from the conventional parallel proportional plus integral plus derivative （PID） controller. The parallel FP ＋ FI ＋ FD controller is actually a nonlinear controller with variable gains. It shows much better set-point tracking, disturbance rejection and noise suppression for nonlinear processes as compared to conventional PID controller.

作者： Sindhiya Arora Siddhartha S. Chandel Sushil Chandra Department of Instrumentation & Control Netaji Subhas Institute of Technology New Delhi India Deen Dayal Upadhyaya Gorakhpur University Gorakhpur Gorakhpur Biomedical Engineering Department INMAS DRDO New Delhi India

This paper presents a fusion approach called Image and Signal Analysis of Multimedia Content (ISAMC) to provide a fully evolved model for emotion recognition using both external (face) and internal (EEG signals) characteristics for the same emotional phenomenon. Both image analysis and EEG signal analysis is done using a video stimulus and based on wavelet approach for feature extraction. This novel methodology provides cross-validation of EEG and Image results with self-assessment of the participants and encourages multi-classification with the use of two different classifiers. The encouraging experimental results prove that the efficiency of this method is very high and due to its simplicity it can be a promising tool for emotion recognition.

Journal of Medical engineering and technology 2013年第2期37卷 86-90页

作者： Godiyal, Anoop Kant Sharma, Richa Joshi, Deepak Bhatia, Dinesh Department of Electrical and Electronics Engineering Graphic Era University Dehradun India Department of Instrumentation and Control Engineering Netaji Subhas Institute of Technology New Delhi India Haryana India

Gender identification has its unique importance in sports and forensic sciences. However, the social issues are major constraints to identify the gender of a human being. A novel approach for gender classification using facial EMG is presented. The time domain features of facial EMGs are explored towards their robustness in gender identification. A Davies-Bouldin index is calculated to evaluate the features. Anterior belly of digastrics along with Orbicularis Oris Inferior showed the promising classification accuracy of 80% with the reported features. A possible enhancement in accuracy could be possible by a larger dataset. © 2013 Informa UK Ltd.

Some Investigations on Fuzzy P+Fuzzy I+Fuzzy D controller for Non-stationary Process

引用

International Journal of Automation and computing 2012年第5期9卷 449-458页

作者： Vineet Kumar B. C. Nakra A. P. Mittal Division of Instrumentation and Control Engineering Netaji Subhas Institute of Technology Delhi University Department of Mechanical Engineering Institute of Technology and Management University Division of Instrumentation and Control Engineering Netaji Subhas Institute of TechnologyDelhi University

The paper addresses the adaptive behaviour of parallel fuzzy proportional plus fuzzy integral plus fuzzy derivative (FP+FI+FD) controller. The parallel FP+FI+FD controller is actually a non-linear adaptive controller whose gain changes continuously with output of the process under control. Two non-stationary processes, whose characteristics change with time, are considered for simulation study. Simulation is performed using software LabVIEW TM . The set-point tracking response of parallel FP+FI+FD is compared with conventional parallel proportional plus integral plus derivative (PID) controller, tuned with the Ziegler-Nichols (Z-N) tuning technique. Simulation results show that conventional PID controller fails to track the set-point and becomes unstable as the process changes its characteristic with time. But the parallel FP+FI+FD controller shows considerably much better set-point tracking response and does not deviate from steady state. Also, a huge spike is observed in the output of PID controller as the reference set-point and process parameters are changed, while the FP+FI+FD controller gives spike free control signal.

Three techniques for constructing reduced order models are presented and compared. The techniques are based on: 1) Model Reduction Using the Routh Stability Criterion by V. Krishnamurthy and V. Seshadri.;2) Higher Order Reduction by Coefficient Comparison by T. Manigandan and N. Devarajan 3) Clustering method for reducing order of linear system using Pade approximation by C.B. Vishwakarma and R. Prasad. In this paper, we have compared the reduced transfer functions obtained from all the three methods and thereafter computed the Relative Integral Square Error (RISE) for different numerical examples by using the above mentioned methods.
