Abstract—Voice coils have been used as actuators for needle free jet injection. This voice coils actuators have slow response which could be compensated by PI control but PI control yields a compensated system with static gains, whereas the application in needle free jet injection requires compensation with dynamic gains. This is due to variation in skin properties. This paper implements adaptive control compensation techniques for the design of controllers for voice coil actuators in the needle free jet injection. The controllers are able to compensate for variation in skin property by adequate tracking of a standard model and the PID controller compensation gain. Modelling and simulations were carried out in MATLAB/SIMULINK and results show a fast response and adequate tracking of the model response irrespective of variations in skin properties.
