Max Q Systems has over 30 years experience in control engineering, from hydraulic actuator and electric motor control in aerospace applications to optical sensors in inspection equipment.

The practice seeks to interrelate physical systems in terms of inputs and outputs. These 'physical systems' can be mechanical, electrical, fluid, chemical, financial and even biological. Engineers design and develop controllers for those systems. The controllers use sensors to measure the output parameters of the device being controlled. These output parameter measurements provide data via a feedback loop back to the main controller. The controller can then implement corrections to achieve the desired output performance. This cycle of measurement and correction  continues until the system is disengaged, or otherwise programmed to stop.

An example of a control system is the cruise control function in an automobile that maintains speed based on the driver's input parameters.  But control engineering can be applied to a wide range of industries: from simple household washing machines to high-performance F-16 fighter aircraft.
