Definitions
- the invention relates to a regulated actuator.
- the invention has for its object to provide a regulated actuator that automatically adapts to various control requirements.
- a regulated actuator which has a motor that actuates an actuator and is powered by a converter, to which converter a digital position controller is assigned, the control algorithm of which is dependent on the output signal, using an adapter connected to the output of the position controller of the position controller is adjustable.
- a reduction in the control interventions is achieved in that a hysteresis element is connected upstream of the position controller.
- a minimum of controller interventions can be achieved in that the switching thresholds of the hysteresis element are controlled as a function of the course of the actual position value.
- a process controller can be superimposed on the position controller.
- control behavior of the process controller can be set according to the respective application, different process processes can be controlled with the actuator.
- 1 denotes a valve which represents the actuator to be actuated by a motor 2.
- a valve 3 is assigned to the valve 1, the output signal of which forms the actual position value for the control processes.
- the motor 2 is fed via a converter 4.
- the converter 4 receives the necessary control signals from a position controller 5.
- This position controller 5 is assigned a control element 6 which is connected with its input to the output of the position controller 5.
- the control element 6 influences the position controller 5 as a function of the signals appearing at its output, ie the control element 6 adapts the control algorithm of the position controller 5 to the behavior of the position control loop.
- a position hysteresis element 7 is also connected upstream of the position regulator 5.
- Corresponding switching shafts are specified by means of such a hysteresis element 7, by means of which the response frequency of the position controller 5 is reduced, since this only responds when these switching thresholds are exceeded.
- the size of these switching thresholds can advantageously also be changed as a function of the course of the actual position value.
- control loop also has a setpoint / actual value comparator 8.
- This setpoint-actual value comparator 8 is supplied via a control line 9 with the output signals of the position transmitter 3 representing the actual value.
- the setpoint-actual value comparator 8 receives a further control line 10 a setpoint.
- the output signals of the setpoint / actual value comparator 8 are switched by means of a changeover switch 11 either directly or via the hysteresis element 7 to the input of the position controller 5.
- the position controller 5 then controls the converter 4 in accordance with the signal received by the target / actual value comparator 8.
- a process controller 12 can also be assigned to the control loop described in order to form the desired value.
- Another setpoint / actual value comparator 13 is assigned to this process controller 12.
- This further setpoint / actual value comparator 13 can be given a setpoint derived from a process via a first line 14 or a constant setpoint internally fixed via a second line 15.
- a selector switch 16 can be used to switch between the two lines 14 and 15.
- the further setpoint / actual value comparator 13 receives the corresponding actual process value via a third line 17.
- a further control element 18 is assigned to the process controller 12, by means of which the control algorithm of the process controller 12 can also be adapted to the behavior of the process control loop.
- the mode of operation of the process controller 12 can thus also be predetermined in accordance with the requirements of the process to be controlled.
- the position controller 5 and the process controller 12 can advantageously be designed as digital, ie as adaptive controllers implemented by software. By means of the control elements 6 and 18, which detect the output signals of these controllers 5 and 12, the controllers 5 and 12 are each switched over to a control type which best corresponds to the control requirements. In this way, optimal control results can be achieved.
