High Precision Force Control

Solve problems of force control in key processes

Core Technology Introduction

SoftForce® Precision Force Control (High-Precision Force Control System), as one of the innovative core technologies of RobustMotion, represents the industry-leading level of high-precision force control systems. This technology utilizes an efficient model predictive control algorithm independently developed by RobustMotion, combined with a high-stiffness force sensor, achieving a control processing frequency of up to 10,000Hz, which means 10,000 calculations per second.Electric actuators equipped with SoftForce® can achieve a force control accuracy of up to ±0.01N (1‰), enabling precise control without overshoot even at high speeds. Through real-time feedback and intelligent adjustment mechanisms, SoftForce® ensures smooth and accurate motion, significantly improving production efficiency and product quality. Moreover, the technology has the advantages of easy integration and maintenance, offering customers a higher cost-performance ratio and lower operational costs.
The flexibility and adaptability of SoftForce® Precision Force Control technology are extremely high, capable of meeting the stringent precision motion control requirements of various industries. It is particularly suitable for ultra-precision assembly, handling, and inspection processes where high precision in force control is required, such as handling high-value or fragile workpieces. Customers can choose the SoftForce® precision force control electric actuator series to meet their specific needs.
In addition, SoftForce® electric actuators can be freely combined into multi-axis precision force control robots, supporting in-depth secondary development, and committed to solving force control challenges in key processes of high-end manufacturing industries.

High-precision Force Control Technology

Softforce® High Precision Force Control

Softforce® Precision Force Control Technology is distinct from the common current loop force control and sensor-based force control solutions found in the market.

RobustMotion's independently developed SoftForce®3.0 high-precision force control system (referred to as "SoftForce® Precision Force Control"), has perfectly resolved the traditional conflict between force output and speed. Even under high-speed conditions, the system maintains stable force output with extremely high precision (up to ±0.01N), and can effectively handle impact forces, ensuring "no overshoot" during high-frequency, high-speed motion.

Comparison of the Effects of Three Force Control Methods

SoftForce®
High-precision Force Control

Force accuracy: ±1‰ / ±0.01N

All six indicators have reached a high and balanced status

Common Sensor Closed-loop
Force Control

Force accuracy:±1%

Difficult to control, Overshoots

Current Loop Force Control

Force accuracy:±5-15%

Poor force accuracy and overshoots

Faster - High Speed Response for Better Performance

Actuators can achieve very high precision of force, position, and speed control attributed to their high-speed response system.

Softer - Real-time Force Feedback, High Force Compliance

When dealing with fragile and delicate workpieces, actuators will activate the flexible force control function. When the workpiece is subjected to excessive force, actuators will activate the flexible force control function immediately to reduce the damage caused by overshoot.

High Frequency and High Speed Without Overshoot

Based on SoftForce® 3.0 high precision force hybrid control algorithm, the F/HF series actuators maintain high force accuracy even under high frequency and high speed motion, ensuring "soft landing" and "no overshoot" to protect the workpiece furthest.
