Abstract: PU) controllers have been broadly used in many areas. Pll) controllers are usually implemented on FPGA for its fast and stable performance. In this dissertation work a digital P11) has been designed and implemented on FPGA for a temperature control system. The temperature control system is modeled. For the designing of the P11) position algorithm has been used. The analog PU) controller equation has been discretized using bilinear transformation method. The parameters of the digital PU) controllers are tuned using Ziegler-Nichols method. Fine tuning is done through Genetic Algorithm approach. The plant taken for real time experimental studies carried out in this dissertation is a third order Linear Time Invariant system which is developed using Control Trainer kit. The controller algorithm developed is synthesized, simulated and implemented on FPGA kit named Spartan 3E xc3s500 fg320 board. The results of the digital PD controller implemented on FPGA have been compared with the result obtained with analog PD controller. 1 Many dynamic systems to be controlled have constant or time varying parameters.. Adaptive control is an approach to control such systems. In this dissertation work model reference adaptive control (MRAC) technique is used to control the system. MRAC based on Lyapunov theory is used to develop control law and adaption law. Two adaptive control techniques are developed based on MRAC. Adaptive control of first order system is designed and simulated in MATLAB-Simulink environment. The developed design is converted in discrete-time and implemented using Xilinx system generator blocks, results are compared with analog design. This technique is extended to second order system.
