| 摘要 |
The invention relates to a P.I.D.-type regulation device with rapid starting especially for the purposes of regulating the temperature of a heated enclosure. It includes a measurement circuit R2, CTN delivering a measurement voltage, a datum generator delivering a reference voltage and a P.I.D.-acting regulation circuit. The regulation circuit consists of a first operational amplifier A1 of non-inverting pseudo-differentiating type receiving at its non-inverting input the measurement voltage Vth and earth on its inverting input, and of a second operational amplifier A2, of inverting and proportional integrator type, receiving on its inverting input the output from the amplifier A1 and on its non-inverting input the reference voltage Vref. Application to thermostatically controlled enclosures for quartz. <IMAGE>
