Automatic switching between position and pressure control on a Pneumatic system was achieved. A GYKS displacement sensor was used for positional feedback and a load cell was used for pressure feedback. Revolutionary I-SAC SW shockless feeddback loop switcher was used to switch between two ISAC C1 controllers for simultaneous position and pressure control.

Speed control of a DC motor was achieved for different loading conditions using I-SAC C1 series controller. The controller parameters were kept same for no load, 3.2 Kg load and 9.54 Kg load. The I-SAC has shown excellent robust performance in achieving the control objective. Please see below the video clips for three different cases.

A 96Kg Load was attached to the piston simulation a plant with high inertia and was made to follow a square positioning signal. Here we have compared the I-SAC's performance with the performance of a P controller.

An iron disk was attached to a ball screw to simulate a load of 5 tons for this setup to simulate a high inertial load plant. A P controller and I-SAC controller, both were set at an initial load of 300Kg and were made to reach the position where the load becomes equal to 5 tonnes.

A pneumatic system was made to follow a square wave and by changing the Time Constant (Tm), it was demonstrated how the system follows absolute square waves and the effect of the Tm variable on the system response.

Step response of a pneumatic plant connected to an I-SAC was tested. The frequency of the signal was taken to the peak speed of the cylinder and response was recorded. Weights of 1Kg, 2Kgs and finally 3Kgs, were added to the plant and response was recorded.
