MTS Systems Corporation , incorporated in 1967, is a global supplier of test systems and industrial position sensors located in Eden Prairie, Minnesota, a southwest suburb of Minneapolis. The company provides mechanical test systems, material testing, fatigue testing and tensile testing services, as well as motion simulation systems and calibration services. Examples of MTS products include: hydraulic actuators,rolling road simulators, shaker tables and medical testing equipment.The Company operates in two segments: the Test segment and the Sensors segment. During the fiscal year ended October 1, 2011, the Test and Sensors segments represented approximately 80% and 20% of the company's revenue, respectively. The Test segment provides testing solutions, including hardware, software and after market support. The Sensors segment products are used by industrial machinery and mobile equipment manufacturers to automate the operation of their products.Test SegmentProducts produced by this segment are used by customers in their development of products and certain applications to characterize the products' mechanical properties. MTS' test systems simulate forces and motions that customers' products are expected to encounter in use. A test system includes a load frame to hold the prototype specimen, a hydraulic pump or electro-mechanical power source, piston actuators to create the force or motion, and a computer controller with specialized software to coordinate the actuator movement and record and manipulate results. MTS' Test segment sells a variety of accessories and spare parts, along with services that include installation, calibration, maintenance, training and consulting. The Test segment has a range of customers in the United States of America, Europe and Asia, which respectively represent approximately 30%, 30% and 40% of total orders.Products and customers are grouped into three global markets: Ground Vehicles, Materials and Structures. The Ground Vehicles market consists of automobile, truck, motorcycle, motorsports vehicle, construction equipment, agricultural equipment, rail, and off-road vehicle manufacturers and their suppliers. Test segment system and service products are used in the Ground Vehicles market for the testing of vehicles, subsystems and components. The Materials market covers diverse industries, including power generation, aerospace, vehicles, and bio-medical. Test segment products are sold worldwide through a direct field sales and service organization as well as through independent representatives.The Company’s products and services support customers in the research and development of products through the physical characterization of materials, such as ceramics, composites and steel. Bio-medical applications include systems to test durability and performance of implants, prostheses, and other medical and dental materials and devices.

Sensors segment products are also used to measure fluid displacement, such as liquid levels for customers in the process industries. The Sensors segment manufactures products utilizing magnetostriction technology. MTS has developed an implementation of the technology, known as Temposonics. Its Sensors segment has a range of customers in the United States of America, Europe and Asia represents approximately 25%, 50% and 25% of orders, respectively. Sensors segment products are sold worldwide through a direct sales organization, as well as through independent distributors.MTS Systems Corp. was fined $400,000 after pleading guilty on March 12, 2008 for submitting false US export license applications on proposed shipments to India. The company admitted to two misdemeanor counts of "false certification or writing" by omitting information linked to nuclear power plant test equipment. In March 2011, MTS disclosed that it was again under investigation and barred from bidding on new government contracts. On September 2011 the ban imposed by the Air Force was lifted, allowing MTS Systems to bid on new government contracts and to continue existing government contracts. MTS Systems settled all investigations with the U.S. Government and took measures to ensure government contracting standards were met. "We are happy to put the government investigation behind us. We have made great progress to ensure we meet the U.S. government's contractor standards and we are committed to meeting these requirements every day," MTS Systems CEO Jeffrey Graves said in a statement.

Systems and methods are provided for controlling the simulation of a coupled hybrid dynamic system. A physical test rig configured to drive the physical structure component of the system and to generate a test rig response as a result of applying a test rig drive signal. A processor is configured with a virtual model of a complementary system to the physical structure component. The processor receives the test rig response and generates a response of the complementary system based on a received test rig response. The system can be driven with a random input. The processor compares the test rig response with the response of the complementary system, the difference being used to form a system dynamic response model.
