Abstract :
Modern satellites need sophisticated
instruments for remote sensing with microlevel accuracy.
This paper features the modelling and design of a
cantilever beam made of aluminium with piezoelectric
sensor and actuator at its free end and a comparative
study of the sensor output voltage with a PID controller as
well as Sliding Mode Controller is being done. In earlier
methods self-tuning sensors and actuators were used. But
it requires coating of the entire beam with piezo film
which is much complex. Also, the output of the sensor will
not be satisfactory. Since the accuracy is much important
in remote sensing applications, separate piezoelectric
sensors and piezoelectric actuators are used by replacing
the piezo film coated beam. This work includes design of
PID and SMC for suppressing the vibration with in
desirable limits against an external disturbance to the
system.
