The resonance frequency shift of the sensor excited by high frequency ac signal is detected wirelessly by measuring the voltage output with change in relative humidity. The structure enabled us to measure the parameter of interest in sealed environment. This paper describes the design and fabrication of the LC sensor, operation of the sensor and its performance characteristics. The experimental results show that the output is linear (±1.8 %), reproducible and has small hysteresis error (± 3%).

There are several limitations that are associated with conventional control philosophies used for this purpose. The modern control techniques are being preferred due to their inherent merits over the conventional control techniques in thermal power plants in general and for superheated steam temperature control in particular. These days, fuzzy logic control concept is one of the intelligent control techniques which has been the revolutionary applications in power system operation and control. In this paper, an attempt has been made to design fuzzy logic based PID controllers for superheater temperature control of a boiler. The PID controllers based on are also designed. Considering a small change in inlet temperature as the disturbance, the PID controllers designed in the study are implemented and the dynamic response plots are obtained. Standard SIMULINK Software is used on MATLAB platform to get the results. The investigations of simulation studies demonstrate the superiority of fuzzy logic based controllers over the conventional PID controllers designed using ZEIGLER-NICHOLS tuning technique.

In this paper a dynamic model of a quadrotor has been developed using MATLAB/SIMULINK software platform. The aim is to model a quadrotor vehicle as realistic as possible. The model is then used to design a PID controller structure to stabilize the roll, pitch and yaw angles of the quad rotor system. The developed systems id tested successfully for number of numerical simulation runs.
