Definitions
- FIG. 1 is a diagram showing the units of a first mode of construction of a control system
- FIG. 2 represents the acceleration diagram obtained as a result of constraints imposed on the derivative of the acceleration
- FIGS. 3A, 3B, 3C represent the geometric shapes of the servo response of the control system as a function of time
- FIG. 6A represents a control system for a discontinuous setting speed
- FIG. 68 represents a control system for an all or nothing speed setting control signal.
- the derivative of the acceleration can assume only three values: +a, 0 a; a is the maximum permitted value for the comfort of the passengers. This is one example of the utilization of the controlled vehicle. These constraints could be different in the case where a vehicle is transporting fragile or other objects.
- K l0 is chosen so that the actual acceleration ys is close to the acceleration ye.
- the control system receives the setting speed signal V It also receives the actual speed signal V obtained on the vehicle. A comparison of these two speeds in the comparator 4 results in a certain signal V V As this signal does not take into account the phase advance, the signal V is used and modified in the device 5 and multiplied by K, in the multiplier 6 for transmission to the comparator 7.
- This comparator 7 provides an output signal P is the LAPLACE, operator. 7
- the diagram illustrates in particular the slowing down of the vehicle which, starting from the station A at zero speed, accelerates to reach a speed corresponding to the setting V The vehicle moves at that speed and then gradually slows down after receiving, at points a, b, c, the settings V V V,- to come finally to a stop at the station B. It is seen from this diagram that a continuous speed is obtained as a result of a discontinuous speed setting.
- step G additively combining the control speed signal V with the actual speed signal V and the positive part of the resulting signal constitutes the actual acceleration signal employed in step G.
