摘要： Disclosed is a method for designing a PID controller, having a control model C ⁡ ( s ) = K P ⁡ ( 1 + K I S λ + K D ⁢ S u ) , wherein KD=aKI, and u=bλ, a and b are proportional coefficients, the control model is reset as C ⁡ ( s ) = K P ⁡ ( 1 + K I S λ + aK I ⁢ S b ⁢ ⁢ λ ) , a transfer function of a controlled object in a control system is set as G ⁡ ( s ) = K s 3 + τ 1 ⁢ s 2 + τ 2 ⁢ s . The method comprises selecting a cut-off frequency ωc and a phase margin φm of the control system; obtaining values of the proportional coefficients a and b, according to an optimal proportion model of control model parameters of the fractional order PID controller, and according to the cut-off frequency ωc and the phase margin φm; calculating amplitude information and phase information of the transfer function at the cut-off frequency ωc; obtaining two equations related to an integral gain KI and a fractional order λ; solving the integral gain KI and the fractional order λ; solving a differential gain KD and a fractional order u; and calculating a proportional gain KP. According to the invention, by establishing a proportional relationship between the integral gain KI and the differential gain KD of the fractional order PID controller as well as a proportional relationship between the integral order λ and the differential order u, the freedom degree of parameters of the fractional order PID controller and consequently the difficulty in parameter setting are reduced.

摘要： The present disclosure relates to a rotation speed sensor, including at least one sensor element to detect a magnetic input signal of the rotation speed sensor, a time watchdog with a programmable time constant and an output control circuit. The time watchdog generates a time-out event when no minimum or maximum or no output switching event of a magnetic input signal of the rotation speed sensor is detected within a time-interval equal to a programmed time constant of the time watchdog. Further, the output control circuit changes the output signal of the rotation speed sensor from a first value to a second value, when a minimum or a maximum or output switching event of the magnetic input signal is detected within the time interval and a change of the magnetic input signal is greater than a predetermined value.

摘要： A technique capable of shortening a period in which value of a PID parameter is outside of an appropriate range is provided. A measured value acquisition functional unit processes a sensing signal of a sensor that measures a barrel and acquires a measured value of the barrel. A storage unit stores a target value of the barrel and a PID parameter. An operation amount calculation functional unit calculates an amount of operation using the PID parameter and a difference between the measured value and the target value. A first output unit and a second output unit output the amount of operation. A first updating functional unit updates the PID parameter through a first update process when the variation range is greater than a first range, and a second updating functional unit updates the PID parameter through a second update process when the variation range is less than a second range.

摘要： A method of process control within a plant includes providing a first and second field device associated with processing equipment sensing a first and second process parameter respectively. The field devices are communicably coupled to a host computer by a communications path including a shared field communications channel portion (shared communications channel) that terminates at a communications device which includes a processor and memory that implements an adaptive scan period determination algorithm (adaptive scanner) which determines a first scan period for the first field device and a second scan period for the second field device each based on a parameter relevant to a data type of the process parameter or communications used. The host computer monitors operations in the plant using sampled data provided by the communications device including data based on the first and second process parameter at their respective scan periods.

摘要： A sensor system for a vehicle includes: at least one sensor unit; and one evaluation and control unit transmitting a synchronization signal via a communication connection to the sensor unit. The sensor unit transmits a sensor signal representing the measured variable via the communication connection to the evaluation and control unit. The evaluation and control unit ascertains an instantaneous signal quality of the received sensor signal and transmits a piece of information about the ascertained instantaneous signal quality to the sensor unit. The sensor unit predefines a modulation amplitude for the transmission of the sensor signal as a function of the ascertained instantaneous signal quality.
