This programmable power supply was design to generate a controllable supply voltage automatically. This programmable power supply consists of the power supply units (PSU) and system control unit. The PSU uses a step-down transformer, rectifier, filter, voltage regulator, and current booster. The control system unit uses a microcontroller, servo motor, keypad, RS232 communication and solid state relay (SSR). The process of automatic voltage setting of this programmable power supply is taken by the servo motor that is controlled by the microcontroller to turn the existing frictionless potentiometer on the voltage regulator. This programmable power supply system is equipped with a short circuit protection unit and over temperature unit. From several testings that have been carried-out, it is concluded that this programmable power supply can generate a voltage from 0 to 20 VDC with error of ± 0,1 VDC and generate current up to 10 A, and also can be operated well within one day."

"Saturation nonlinearities are ubiquitous in engineering systems, every physical actuator or sensor is subject to saturation owing to its maximum and minimum limits. Input saturation is an operating condition that is well known to the control community for its “side effects”, which cause conventional controllers to lose their closed-loop performance as well as control authority in stabilization. Therefore, the practical application of control theory cannot avoid taking into account saturation nonlinearities in actuators, explicitly dealing with constraints in control design."

"Applied control system design examines several methods for building up systems models based on real experimental data from typical industrial processes and incorporating system identification techniques. The text takes a comparative approach to the models derived in this way judging their suitability for use in different systems and under different operational circumstances. A broad spectrum of control methods including various forms of filtering, feedback and feedforward control is applied to the models and the guidelines derived from the closed-loop responses are then composed into a concrete self-tested recipe to serve as a check-list for industrial engineers or control designers. System identification and control design are given equal weight in model derivation and testing to reflect their equality of importance in the proper design and optimization of high-performance control systems.
