This has become possible because of the developments in the semiconductor manufacturing technologies (both bipolar as well as CMOS). During the last two decades various modifications have been done in the architecture of the current conveyor and many derivatives of this block have appeared in the literature. Voltage differencing current conveyor (VDCC) combines the features of a current conveyor and an operational transconductance amplifier. Voltage differencing current conveyor can be used to perform the entire regular signal processing applications (summation, differencing, scalar multiplication, amplifiers and filters etc.). The present work deals with the signal processing applications of the voltage differencing current conveyor in amplifiers and filters. A novel multifunction filter with tunability properties similar to the Tow- Thomas biquad filter has also been proposed. All the circuits presented in the dissertation have been simulated in PSPICE. 2016-05-01T00:00:00Z http://dspace.dtu.ac.in:8080/jspui/handle/repository/13891 Title: INTELLIGENT CONTROL OF ROBOTIC SYSTEM Authors: SINGH, VISHWA PRATAP Abstract: The problem of manipulator control is highly complex problem of controlling a system which is multi-input, multi-output, and non-linear and time variant. A number of different approaches presently followed for the control of manipulator vary from PI, PID And Fuzzy Logic Controller to very complex, intelligent, self-learning control algorithms. This report presents a comparative study of simulated performance of some conventional controllers like the simple PI, PID controllers And Fuzzy Logic control,. IAE is used for comparison as performance index. The study concludes that the PID controller in general performs better then PI controllers. When the unmodeled term is added to the model, PID and PI control perform badly. Computed torque control also affected but they do well. A Fuzzy Logic controller combines the advantage of PI And PID to achieve the goal of robot control Arm, performs better in PI And PID controllers and also shows that Fuzzy Logic controller are better even when unmodeled terms are added to the model.
