    This paper presents a new programmable analog electronic proportional-integral-derivative controller circuit using current conveyor transconductance amplifiers as active elements. Unlike previous works, proportional controller, proportional-integral controller, proportional-derivative controller and proportional-integral-derivative controller of proposed structure can be programmed by the bias currents. Also proportional gain, integral time constant and derivative time constant can be electronically controlled. The use of grounded capacitor makes the proposed structure suitable for integrated circuit implementation. The simulation results are used to confirm the workability of the proposed circuit.

    This paper presents a voltage-mode proportionalintegral-derivative controller using fully differential current conveyors as active elements. The proportional gain, integral time constant and derivative time constant can be orthogonally controlled. The proportional, proportional-integral, proportionalderivative and proportional-integral-derivative controllers can be obtained by appropriately connecting the input and output terminals. The circuit possesses high-input impedance which is advantageous for cascade connection. The proposed structure is highly suitable for integrated circuit implementation by using only grounded passive comments. The PSPICE simulation results are included to confirm the workability of the proposed circuit. © 2014 IEEE.

    Voltage-mode PID controller using DDCCs and all-grounded passive components
    (2013-01-01)
    Kumngern, Montree
    This paper presents a new voltage-mode proportional-integral-derivative (PID) controller using the differential difference current conveyors as active elements. The proposed PID controller uses all-grounded passive components which is highly suitable for integrated circuit implementation. The proportional gain, the integral time constant and the derivative time constant parameters can be independently controlled. For controlling the PID controller parameters, the circuit dose not need passive component-matching condition. The PSPICE simulation results are used to confirm the characteristics of the proposed PID controller. © 2013 IEEE.
